[Intel-gfx] [PATCH 14/22] drm/i915: Don't treat differently sized rotated views as equal

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

In case we have multiple different rotated views into the same object,
each one may need its own vma due to being of different sizes. So don't
treat all rotated views as equal.
