Support backlight control via lid only
The old backlight_x86 code did
(backlight enable) = (lid is open) && (GPIO request from AP)
Newer systems will AND those signals in hardware. Support those
systems by separating CONFIG_BACKLIGHT_LID and
CONFIG_BACKLIGHT_REQ_GPIO, and add tests for the case where the enable
signal is dependent only on the lid position.
