This version moves the EFI handling back to the gmux driver. Why?
Because the platform maintainer just NACKed the EFI backend driver, so i
cant do anything

After reading this, i wonder why this functionality should live inside the kernel after all.
Systemd seems to already store the backlight brightness during shutdown/reboot, so maybe
having a small oneshot service that synchronizes those values with the EFI variable during
shutdown/reboot might be easier?
