[PATCH libdrm] modetest: Allow full testing of primary planes

[Ville Syrjala]

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

Allow the user to override the default configuration set by setcrtc
for the primary plane. On some hardware primary planes can be freely
positioned/sized, and it'd be nice if we can actually test that feature.
