media: nxp: imx8-isi: crossbar: Add get_frame_desc operation

Browse Source 
Implement the get_frame_desc pad operation for the crossbar subdev using
the v4l2_subdev_get_frame_desc_passthrough() helper. This allows the
crossbar to properly propagate frame descriptors from its sink pads to
its source pads, which is necessary for proper stream configuration in
multiplexed streams scenarios.
