media: nxp: imx8-isi: Add stream ID validation for crossbar routing

Browse source

Add validation to enforce hardware constraints that were previously
missing in the crossbar routing configuration:

- SOURCE stream must be 0 (ISI pipes are hardcoded to stream 0)

This check complements the existing memory input validation and ensures
that all routing configurations respect hardware limitations.
