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.
