drivers/intel/gma: fold gma.asl into default_brightness_levels.asl

Including gma.asl at the platform level (vs the board level)
means that even desktop boards need to include the default
brightness levels, which makes no sense. To begin to clean this up,
include gma.asl in default_brightness_levels.asl (as well as
the handful of board-specific brightness files) and remove it
from the various platforms.

A follow-on commit will remove default_brightness_levels.asl
from all boards which lack an internal display.
