media: rzg2l-cru: csi2: Implement .get_frame_desc()
The RZ/G2L CRU requires information about which VCx to process data from,
among the four available VCs. To obtain this information, the
.get_frame_desc() routine is implemented. This routine, in turn, calls
.get_frame_desc() on the remote sensor connected to the CSI2 bridge.
