New System76 ACPI driver

System76, one of the few Linux-centric OEMs, has started to offer coreboot on some of their systems.

Apparently, the new System76 firmware includes a new ACPI table, though I can’t seem to find that table documented on the ACPI spec list (which appears to have been last updated Summer of 2019).

Add System76 ACPI driver, which adds support for Fn-Fx key combinations, keyboard backlight, and airplane mode LEDs on System76 laptops running open source firmware.
