Commit Message

  Add bindings for J721S2 BCDMA instance dedicated for Camera
Serial Interface. Unlike AM62A CSI BCDMA, this instance has RX
and TX channels but lacks block copy channels.

V1->V2:
     * Move J721S2 BCDMA entry to else condition to avoid failure
     with AM62A BCDMA.

Avoid if:else:if:else and alike. I asked to add one more if covering
this case.
