drm/i915: Stuff rotation params into view union

We don't need 2 separate unions. Note that this was done intentinoally Author: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Date: Wed May 6 14:35:38 2015 +0300 drm/i915: Add a partial GGTT view type on Tvrtko's request, but without a clear justification. Rotated views are also not checking for matching paramters in i915_ggtt_view_equal, which seems like a bug. But this patch here doesn't change that.
