tests: check plane rotation is reset after the VT mode is restored

Browse Source 
Make sure the rotation is reset after the VT mode is restored by
collecting the unrotated CRC and comparing with the CRC value after VT mode
has been restored. The CRC is used to ensure the hardware state is checked,
rather than any software state.
