[PATCH 11/12] drm/i915/selftests: Use i915_gtt_view_is_*()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Replace the naked GTT view type checks with the new
i915_gtt_view_is_*() helpers. This isolates some of
the code from GTT view implementation details.
