mb/google/eve: Use keyboard backlight for proof-of-life at boot
This feature was originally present and then dropped, but turns out
that users prefer it. Set the backlight to 50% in romstage, back to
zero in ramstage; skip enabling on the S3 resume path.
TEST=build/boot google/eve, verify keyboard backlight turns on/off
as expected.
