media: imx5/6/7: csi: Mark a bound video mux as a CSI mux

Browse source

For i.MX5/6, if the bound subdev is a video mux, it must be one of the
CSI muxes, and for i.MX7, the bound subdev must always be a CSI mux.

So if the bound subdev is a video mux, mark it as a CSI mux with a new
group id IMX_MEDIA_GRP_ID_CSI_MUX.

In the process use the new group id in csi_get_upstream_endpoint(), and
do some cleanup in that function for better readability.
