[PATCH 8/9] drm/i915: Relocate xe AUX hack

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

Move the xe AUX neutering out from skl_get_plane_caps() into the
caller so that it'll be easier to refactor skl_get_plane_caps()
into a more readable shape. This isn't really hardware specific
anyway, and just some kind of bug/misfeature of xe.
