This patch is adding NV12 support to skylake sprite plane programming. It is covering linear/X/Y/Yf tiling formats for 0 and 180 rotations. For 90/270 rotation, Y and UV subplanes should be treated as separate surfaces and GTT remapping for rotation should be done separately for each subplane. Once GEM adds support for seperate remappings for two subplanes, 90/270 support to be added to plane programming.
