soc/intel/common: Hook up GMA ACPI brightness controls
Add framework to hook up the generic src/drivers/intel/gma ACPI backlight control for platforms using SOC_INTEL_COMMON_BLOCK_GRAPHICS. Add a weak function to get the struct i915_gpu_controller_info needed to generate the SSDT, defaulting to NULL, which SoC's will override. Each SoC will need to override intel_igd_get_controller_info, and individual boards will need to populate the struct in order for the backlight control methods to be added to the SSDT.
