soc/intel/braswell: add ACPI backlight support

Add hook to generate ACPI methods in SSDT for screen backlight control.

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.
