media: ti: cal: use frame desc to get vc and dt
Use get_frame_desc() to get the frame desc from the connected source,
and use the provided virtual channel and datatype instead of hardcoded
ones.
get_frame_desc() can contain multiple streams, but as we don't support
multiple streams yet, we will just always use the first stream.
If the source doesn't support get_frame_desc(), fall back to the
previous method of always capturing virtual channel 0 and any datatype.
