Add power-gpios device-tree binding property to power on module before
communicating with it. This pin is called CHIP_PU in case of ESP32{,-S2}
and CHIP_EN in case of ESP8266. Dedicated reset pin is available only on
the latter, however Espressif recommends (in ESP8266 Hardware Design
Guidelines) to use CHIP_EN instead. Follow those recommendations and use
power-gpios to reset chip if that is provided over device-tree.
Configure power-gpios and reset-gpios as inactive by default, so that
chip becomes ready after executing esp_reset() function, either if one
or both are provided over device-tree.

Most DT bindings use reset-gpios name when there is a pin to reset whole
chip. Rename wifi-reset-gpios to reset-gpios to be more consistent
between various drivers. Additionally this prevents confusion, as
somebody might think that this pin resets only WiFi, which is not true.

Allow to reconfigure UART baudrate on ESP and on host MCU, so a
non-default baudrate can be used for communication. This option helps
for example to increase network bandwidth without touching ESP chip
firmware.

With the introduction of the new device-tree macros it is now possible
to use the settings for speed and flow-control from the bus node instead
of having the same properties on the esp node itself.

This adds support for the Espressif ESP8266 and ESP32 devices to be used
as peripherals on a UART.
There are two main AT command versions that can be selected, 1.7 and
2.0. Since they behave a bit different it is important to select the
one that matches the used in the firmware on your device.
When downloading large amounts of data it is highly recommended to
enable CONFIG_ESP_PASSIVE_TCP and flow control on the UART so that
data is not lost due to UART speed or receive buffer size.
Currently unsupported:
- Changing UDP endpoint with a sendto()
- Bind to a specific local port
- Server socket operations, ie listen() and accept()
Official AT firmware for ESP8266 and ESP32 can be found at:

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.

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.
