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.
