[Intel-gfx] [PATCH v4 05/12] drm/i915: Use fb modifiers for display tiling decisions

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Soon the fence tiling mode may not always match the fb modifier
even for X tiled buffers. So let's use the fb modifier
consistently for all display tiling decisions.
v2: Rebased due to s/ring/engine/
v3: Rebased due to s/engine/ring/ O_o
v4: Rebase due to i915_gem_object_get_tiling() & co.
