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

We're currently not providing the possible_crtcs mask to
drm_universal_plane_init() for primary/cursor planes. While that does
work on account of drm_crtc_init_with_planes() filling those up
for us, it's inconsisten with what we're doing for sprite planes.

Let's just always pass the possible_crtcs bitmask to
drm_universal_plane_init(). This does assume that crtc->index
== pipe. But we're already making that assumption elsewhere so
it doesn't seem like a very big sin here.
