[PATCH 3/9] drm/i915: Move nv12 chroma plane handling into intel_surf_alignment()

[ville.syrjala at linux.intel.com]

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

Let's try to keep the alignment requirements in one place, and so
towards that end let's move the AUX_DIST alignment handling into
intel_surf_alignment() alongside the main surface alignment stuff.
