intel: Don't map regions with drm_intel_gem_bo_map_gtt() unless they're tiled.

Browse source 
This fixes a regression in region read performance that came in with the
texture tiling changes.  Ideally we'd have an access flag coming in so we
could also use bo_map_gtt for writing, like we do for buffer objects.

Bug #22190
