controlling, volume, brightness, etc in hardware.

-Subject: [PATCH 1/1] t480 hack: turn off the dgpu
-
-too buggy, in mkukri's testing. just turn it off.
-
-thanks go to mkukri for showing me how to turn this off.
-as nicholas explained to me, if there's no nvram on this board,
-coreboot can't use a static option table, because that works by
-copying those settings to the nvram.
-
-so we just have to hardcode for the time being
