drm/i915: Introduce crtc_state->update_planes bitmask
Keep track which planes need updating during the commit. For now
we set the bit for any plane that was or will be visible (including
icl+ nv12 slave planes). In the future I'll have need to update
invisible planes as well, for skl plane ddbs and for pre-skl pipe
gamma/csc control (which lives in the primary plane control register).
v2: Pimp the commit message to mention icl+ nv12 slave planes (Matt)
