Subject: [media] v4l: vsp1: Set the SRU CTRL0 register when starting the
 stream

commit f6acfcdc5b8cdc9ddd53a459361820b9efe958c4 upstream.

Commit 58f896d859ce ("[media] v4l: vsp1: sru: Make the intensity
controllable during streaming") refactored the stream start code and
removed the SRU CTRL0 register write by mistake. Add it back.

Fixes: 58f896d859ce ("[media] v4l: vsp1: sru: Make the intensity controllable during streaming")
