[v2,00/10] media: Multiplexed streams for R-Car CSI-2 and ADV748x

Hello,
   this series build up several other branches:

- Tomi's tomba/multistream/work-v11
- Niklas' CHSEL rework:
  "media: rcar-{csi2,vin}: Move to full Virtual Channel routing per CSI-2 IP"

The series makes adv748x a fully multiplexed device which can direct the video
stream on different source pad streams which select the virtual channel.

The CSI-2 support was sent already, but this time has been rebased on Niklas'
chsel rework. The CSI-2 is a multiplexed receiver with a fixed routing table
as the routing towards VIN is controlled by link enablement.

Finally VIN needs a little adjustment to support multiplexed transmitters.

v1 -> v2:
- rebased on Tomi's v11
- Modified R-Car CSI-2 VC handling as suggested by Niklas. Now I can capture
  all CSI-2 Virtual Channel from every VIN instance freely \o/
