drivers/intel/gma: put controller in separate header
Including i915.h just for the GMA/SSDT related functions means dragging along all of i915_reg.h as well, which is problematic since some platforms (like Apollo Lake) use overlapping symbols. To avoid this conflict, break out the GMA/SSDT bits into their own header which can be included without conflict.
