[Intel-gfx] [PATCH v2] kms_universal_plane: subtest for yuv pixel format in primary plane

[Kumar, Mahesh]

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

V2: Revert chnages for MAX_PLANE count as per nabendu's comment. These
changes are already floating for review.
