soc/intel/broadwell: add ACPI backlight support
Add framework to generate ACPI methods in SSDT for
screen backlight control. Adjust params for gtt_ methods
to match prototypes in i915.h and avoid conflicts.
To make use of this, individual boards will need to
include default_brightness_levels.asl in their dsdt, as
well as add 'register "gfx" = "GMA_STATIC_DISPLAYS(0)"' to
their devicetree.
