Andrzej Puzdrowski af0abb2b8d doc/reference: move the settings doc higher
Settings documentation was placed under storage paragraph
in documentation tree, which suggested that it was another
storage solution. In fact settings uses storage modules as
its persistent storage back-end.

This patch creates dedicated run-time configuration paragraph
which aim to explain existence (and emphasize) of common run-time
configuration system in Zephyr-RTOS and rationale for using it.
The Settings paragraph is placed under this paragraph as it is only
sub-module which implements the solution.

Marti Bolivar 27e5dd131f doc: s/device tree/devicetree/
DTSpec writes this as a single word, presumably to make it easier to
grep for / more precise. Follow along in the rest of the docs now that
our main DT docs page agrees with this usage.

Ulf Magnusson a84ded74ea dts: Replace status = "ok" with status = "okay"
The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.

The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.

The replacement was done with

    git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'

David B. Kinder 6000a6205a doc: prepare for improving doc API linking
Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all".  This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.

This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)

This is a start to address issue #14313

Laczen JMS 7989801966 fs/nvs: Improve init speed and remove fs->locked
This patch removes the free space calculation from nvs initialization.
The available space can be calculated if required using the routine
nvs_calc_free_space.

This patch also removes the locked state of nvs, it is not possible to
get in a locked state.

Changes:

Removed locked state and free_space from the nvs structure.

nvs_reinit(): has been replaced with by an internal only function
_nvs_startup().

nvs_write(): removed the possibility to place the file system in a
locked state, if to many gc operations are required it will return
-ENOSPC.

ssize_t nvs_calc_free_space(): introduced, calculates the free space
that is available in the nvs file system.
