kms_plane: Add test that suspends/resumes before getting crc

Browse Source 
This adds a test that does a suspend/resume cycle between configuring
a plane and getting the crc value for the pipe. The intention is to
test if the user requested stated is restored properly, instead of
being clobbered by the state read out from the hardware.
