In case the PRPVF is not connected directly to CSI, the PRPVF subdev
driver won't find the CSI subdev and will not configure the CSI input
mux. This is not noticable on the IPU1-CSI0 interface with parallel
camera, since the mux is set "correctly" by default and the parallel
camera will work just fine. This is however noticable on IPU2-CSI1,
where the mux is not set to the correct position by default and the
pipeline will fail.
Add similar code to what is in PRPVF to VDIC driver, so that the VDIC
can locate the CSI subdev and configure the mux correctly if the CSI
is connected to the VDIC. Make the PRPVF driver configure the CSI mux
only in case it's connected directly to CSI and not in case it is
connected to VDIC.

Same here, I cannot merge with out Acks since I don't know the details
of the imx hardware.

I'm marking this patch as Obsoleted since there has been no activity for a long
time.

Hi Hans, yes that's fine. IIRC this issue has been fixed a different way.
