  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.

You now require 5 reg items on ti,am62a-dmss-bcdma-csirx. I don't think
you tested your DTS against this change. Rework the else: so it will
match specific variant (if:).

Best regards,
Krzysztof

Thank you for the review, Sorry, I did not have the ti,am62a-dmss-bcdma-csirx
instance added while I tested this change, I have made the update you suggested,
checked DTS with the nodes added and sent a v2 now.

Thanks and Regards,
Vaishnav
