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 SARA-R4 series modules from U-Blox are size-optimized LTE-M /
NB-IoT and EGPRS modules designed for low power consumption and
longer battery life.
The binding identifies the UART device, power GPIO and reset GPIO
lines.

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.

Add 'generation: define' directive to 'compatible' property.
When existing for a type of device, move compatible property
description in device base structure (eg: i2c.yaml)

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.
