parentdrm/i915: intel_wait_for_register_fw to uncore (diff)

drm/i915: switch intel_wait_for_register to uncore
The intel_uncore structure is the owner of register access, so subclass the function to it. While at it, use a local uncore var and switch to the new read/write functions where it makes sense.
