Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

We generated a define for each instance to convey its existance of the
form:
#define DT_<COMPAT>_<INSTANCE> 1
However we renamed all other instance defines to be of the form
DT_INST_<INSTANCE>_<FOO>. To make things consistent we now generate a
define of the form:
#define DT_INST_<INSTANCE>_<COMPAT> 1
We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses
to use the new form.
Fixes: #17650

Not all serial drivers support ASYNC operation and if they do,
they might not support it on every SoC.
Add the SERIAL_SUPPORT_ASYNC option to indicate ASYNC operation
is availiable.

This adds support for the async API for SAM0 SERCOM USARTs using
DMA to drive the device.
Tested on SAMD21 with a few trivial programs and with
tests/drivers/uart/uart_async_api.

Make sure that when e.g. CONFIG_SERIAL is set, CONFIG_UART_SAM0 is
selected automatically when the sam0 SoC family is used.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'
