google/lars: Turn on keyboard backlight in romstage
Cherry-pick from Chromium:
a60ac10 [Lars: Turn on keyboard backlight in romstage]
Use the keyboard backlight to provide indication that the system is
booting. This is useful for determining that a system is in S0 and
is running BIOS code.
TEST=boot on Lars and see keyboard backlight come on early
