LLVM/clang is not used for any compilation due to it not supporting the
8-bit architectures we use (MCS-51, AVR). This means we are effectively
installing 250+ MiB of dependencies for a C formatting tool.
Replace it with uncrustify, which uses only ~600 KiB of space and has
more granular control of formatting (800+ options).

SDCC 4.3.3 complains about the declaration not matching the prototype:
error 283: function declarator with no prototype
Add `void` to the AVR functions as well, even though no warning is
issued by GCC.

Use the default mode for reading the keyboard scan matrix when being
used as a keyboard. There should be no perceived change in behavior, but
should make the code easier to understand.
Note: `KSO[17:16]` are configured by `GPCRC` on boards that use them.
They are now set to alternate function to use in KBS mode rather than
GPIO mode, with the pull-up enabled to prevent them from floating when
configured as open-drain.
As part of this change, we now only read the hardware matrix state once
upfront, instead of on every iteration through the loop applying the
logic.
Tested by verifying that typing still works on darp9.

Enable PWRSW WDT 2 and use the default timeout of 10 seconds.
Allows forcing an EC reset in case it gets into an invalid state.

Update .clang-format for LLVM 14.0, available on Ubuntu 22.04.
There is still plenty that clang-format sucks at or does wrong, so
either add some more blocks to disable it, or just put up with it.

Add a new wireless object for controlling WLAN power state. Change the
power sequence to enable WLAN at board init and disable it at power off.
Newer galp5 units sold to customers have an issue where they do not
fully power off. This is apparently somehow caused by `WLAN_PWR_EN`.
The unit received for development do not have this issue.
