The media device operations structure will be different deepening on
what media graph layout is used. Instead of hard-coding the R-Car CSI-2
layout allow the operations to be passed as an argument.

I would continue the effort of using the csi2_ prefix for CSI-2
related fields. Just a nit, the change looks good
