drm/i915: Add tiling attribute to the modifier descriptor

Add a tiling atttribute to the modifier descriptor, which let's us
get the tiling without listing the modifiers twice.

v1-v2: Unchanged.
v3:
- Initialize .tiling to I915_TILING_NONE explicitly (Ville)
- Move from previous patch lookup_modifier() to here, where it's first
  used.
