mb/google/guybrush: enable display backlight in ramstage
Commit c7204b5a4 [mb/google/guybrush: Enable backlight in the OS]
disabled the GPIO for the display backlight in favor of using ACPI
to enable it, but this breaks display output for payloads which do
not/can not enable the backlight GPIO themselves (edk2, grub, SeaBIOS).
Re-enable the GPIO for display backlight so that payloads other than
depthcharge work properly.
TEST=build/boot google/dewatt with Tianocore payload, verify payload
display visible.
