kms_universal_plane: subtest for yuv pixel format in primary plane

Commit Message

Kumar, Mahesh July 20, 2015, 3 p.m. UTC

This test commit YUV framebuffer in primay plane. I'm using empty FB,
because this fulfills the purpose of testing YUV.

Increase IGT_MAX_PLANES to 5 and add enum for IGT_PLANE_4, as in Broxton
we have 4Plane+1cursor plane.
