soc/intel/apollolake: Hook up GMA ACPI brightness controls
Add struct i915_gpu_controller_info for boards to supply info needed
to generate ACPI backlight control SSDT.
Hook into soc/common framework by implementing intel_igd_get_controller_info().
Add Kconfig entries to set the correct register offsets for backlight
frequency and duty cycle.
