The X13s does have EC-generated hotkey events similar to the T14s.
I left the input functionality out intentionally to keep the initial
driver focused on keyboard-backlight control and power management.

I've identified several X13s event codes in the ACPI DSDT, including
the programmable F12 key and call-control keys. I think it makes sense
to add input support as a follow-up once the event mappings and
expected behavior have been verified on hardware.
