Move display related members under drm_i915_private display sub-struct.
Prefer adding anonymous sub-structs even for single members that aren't
our own structs.
Abstract mmio base member access in register definitions in a macro.

ugh, and I thought we wouldn't have so many implicit params anymore.
Mind adding a "TODO: remove implicit dev_priv parameter" ?
