[PATCH i-g-t 11/12] tests/kms_big_fb: Test planar YCbCr formats

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Panning around inside planar YCbCr framebuffers is a bit
more involved that the RGB counterpart. It seems prudent
to test that we are correctly handling these case.

We'll manually trick rendercopy to also copy the chroma
plane for us. It might be nice to make rendercopy eventually
handle this entirely on its own, but for now we'll take this
slight shortcut.
