drm/i915/gmbus: stop using implicit dev_priv in register definitions
Since the beginning of time, we've implicitly assumed dev_priv is present as a local variable in many places. We've gone a long way in removing many of them, but the register macro definitions are the last holdout. Remove them from the gmbus macros.
