[Intel-gfx] [PATCH 4/8] drm/i915: Use {active, scaled}_planes to compute ilk watermarks

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use the {active,scaled}_planes bitmasks from the crtc state
rather than poking at the plane state directly. One step
towards eliminating the last use of the somewhat questionble
intel_atomic_crtc_state_for_each_plane_state() macro which
peeks into the plane state without actually holding the plane
mutex.
