[PATCH] drm: drm_rect and clipping for intel sprite planes

I'm re-sending this whole plane clipping series, as it has been a quite while since the last time I posted it. Laurent went through patch 1 and I made the requested changes, and I also fixed a minor issue in patch 3 that I spotted myself. The other patches are unchanged and looking for volunteers
