Subject: [PATCH 0/2] platform/chrome: cros_kbd_led_backlight: Automatically enable keyboard backlight control if feature present in EC

The keyboard backlight control is not enabled by default on all devices
with a Chromium EC, e.g. my Framework 13. This patch series enables it
if the feature is present in the EC, instead of relying on
`of_match_table`s or whatever.

These patches are tested and working on my Framework 13, and KDE's
keyboard brightness slider even works. It's also gone though a couple of
reboot & sleep cycles without issue.

Also this is my first time submitting a patch to the kernel, and I'm keen
to do more, so please let me know if I've done anything wrong.

Thanks,
Steve
