Adding support for Quectel BG95 Modem offloaded driver
to zephyr.
The driver currently implements only the
client side functions of the "socket_op_vtable", and
so cannot be used for cases where Zephyr acts as a
server. Moreover the driver only supports TCP for now.
Looking through the guides, the same driver should be
usable for BG96 (and other modems) except for the modem
boot-up sequence. Hence its named as "bg9x" instead of
"bg95".
Tested extensively with Zephyr acting as MQTT endpoint
and publishing / subscribing data to / from an MQTT
broker.

The driver utilizes the CONFIG_NET_OFFLOAD setting to avoid the
normal handling of IP packets, and instead uses a socket-like
UART interface to handle incoming and outgoing data via AT commands.

Add any useful information from 'title:' to the 'description:' strings
(e.g. explanations of acronyms), and remove 'title:' as well as any
copy-pasted "this binding gives a ..." boilerplate.
Also clean some description strings up a bit.
Some other things could probably be cleaned up (replacing 'GPIO node'
with 'GPIO controller' on controllers for consistency, for example), but
I kept things close to the original to avoid accidentally messing up.

With https://github.com/zephyrproject-rtos/zephyr/pull/20185, multi-line
descriptions will be formatted nicely, but using '>' breaks it, because
it removes internal newlines (including between paragraphs).
See https://yaml-multiline.info/.
Replace 'description: >' with 'description: |' to encourage '|'. That'll
prevent '>' from getting copied around and messing up long descriptions.
This will lead to some extra newlines in the output, but it's fine.
Line-wrapping messes up any manual formatting.
The replacement was done with
$ git ls-files 'dts/bindings/*.yaml' | \
xargs sed -i 's/description:\s*>/description: |/'

Instead of
properties:
compatible:
constraint: "foo"
, just have
compatible: "foo"
at the top level of the binding.
For backwards compatibility, the old 'properties: compatible: ...' form
is still accepted for now, and is treated the same as a single-element
'compatible:'.
The old syntax was inspired by dt-schema (though it isn't
dt-schema-compatible), which is in turn a thin wrapper around
json-schema (the idea is to transform .dts files into YAML and then
verify them).
Maybe the idea was to gradually switch the syntax over to dt-schema and
then be able to use unmodified dt-schema bindings, but dt-schema is
really a different kind of tool (a completely standalone linter), and
works very differently from our stuff (see schemas/dt-core.yaml in the
dt-schema repo to get an idea of just how differently).
Better to keep it simple.
This commit also piggybacks some clarifications to the binding template
re. '#cells:'.

The 'category: required/optional' setting for properties is just a
yes/no thing. Using a boolean makes it clearer, so have
'required: true/false' instead.
Print a clear error when 'category:' is used:
edtlib.EDTError: please put 'required: true' instead of 'category:
required' in 'properties: foo: ...' in
test-bindings/sub-node-parent.yaml - 'category' has been removed
The old scripts in scripts/dts/ ignore this setting, and only print a
warning if 'category: required' in an inherited binding is changed to
'category: optional'. Remove that code, since the new scripts already
have the same check.
The replacement was done with
git ls-files 'dts/bindings/*.yaml' | xargs sed -i \
-e 's/category:\s*required/required: true/' \
-e 's/category:\s*optional/required: false/'
dts/binding-template.yaml is updated as well.

This adds support for SARA-U2 modems. They have different timings on
the PWR_ON pin, don't support AT+CESQ and require a manual GPRS
connection setup.
The VINT pin is used as a more reliable and faster way to power on the
modem.

No binding has anything but 'version: 0.1', and the code in scripts/dts/
never does anything with it except print a warning if it isn't there.
It's undocumented what it means.
I suspect it's overkill if it's meant to be the binding format version.
If we'd need to tell different versions from each other, we could change
some other minor thing in the format, and it probably won't be needed.
Remove the 'version' fields from the bindings and the warning from the
scripts/dts/ scripts.
The new device tree script will give an error when unknown fields appear
in bindings.
The deletion was done with
git ls-files 'dts/bindings/*.yaml' | xargs sed -i '/^\s*version: /d'
Some blank lines at the beginning of bindings were removed as well.

Now that the generation script doesn't look at the "generation" in the
YAML, we can remove it from the binding files.

YAML document separators are needed e.g. when doing
$ cat doc1.yaml doc2.yaml | <parser>
For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.
Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).
The replacement was done with
$ git ls-files '*.yaml' | \
xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'
First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.
Some redundant blank lines at the end of files were cleared with
$ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'
This is more about making sure people can understand why every part of a
binding is there than about removing some text.

Move common properties like 'compatible', 'reg', 'reg-names',
'interrupts', 'interrupt-names', and 'label' into one common base.yaml
that all the other yaml's can inherit from. This removes both
duplication and inconsistent definition.
The device specific yamls just need to say if a property is 'required'
or not.
NOTE: due to some generation conflicts we did not covert
'soc-nv-flash.yaml' to use base.yaml.

The label binding was missed during initial development of the
WNC-M14A2A modem. Let's add the binding so that during the
migration to a shield, we can update the DTS correctly.

When the WNC-14A2A modem binding was originally introduced, I thought
the base_label would shorten the define keeping the result short and
easily portable. Turns out with the latest changes, it has a side
effect of removing the "DT_*" prefix which is breaking the build.
Let's remove "base_label" from the modem binding and adjust all of
the dts_fixups referring to the WNC14A2A defines.
NOTE: This commit moves the left-over WNC14A2A dts_fixup defines from
the nRF52 soc into samples/net/lwm2m_client as the new values.
They will stay there until the modem can be re-configured as a shield.

The 'id' field was never used and tended to just have the compat of the
node. Lets remove it and removed some code in extract_dts_includes.py
related to it. Added a warning if 'id' is set in a yaml so we can
remove it going forward.

The WNC-M14A2A (LTE / LTE-M) modem is presented as an Arduino-
compatible shield via AT&T's IoT Starter Kit v1.0. It was
originally intended to work with the FRDM-K64F board, but
in theory as long as the right pins are configured it can
work with any board that supports Arduino-compatible headers.
The driver utilizes the CONFIG_NET_OFFLOAD setting to avoid the
normal handling of IP packets, and instead uses a socket-like
UART interface to handle incoming and outgoing data.
