google/lulu,gandof: set kb backlight on boot
Set keyboard backlight to 75% on boot, except when resuming
from S3. This enables the backlight at a reasonable level
prior to the OS driver taking over, providing early proof-of-life
and enhanced usability in grub etc.
Uses same method as other google boards with a keyboard backlight
(chell, link, samus). 75% value determined based on user feedback.
TEST: boot google/lulu,gandof boards, observe keyboard backlight
enabled in pre-OS environment.
