drm/i915: Use enum plane_id for frontbuffer tracking

Browse Source 
Replace the ad-hoc plane indexing scheme used by the frontbuffer
tracking with enum plane_id.

The old video overlay not being part of the plane_id namespace
will just be given the high bit.

v2: Drop the unintended whitespace change (Chris)
