[PATCH 1/9] drm/i915: Remove debug prints from primary plane update funcs

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

These are now called from the plane commit hooks, so they really need to
be fast or else we risk atomic update failures. So kill the debug prints
which are slowing things down massively.
