From: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx>
The Salvator boards use an ADV7482 receiver for HDMI and CVBS inputs.
Provide ADV7482 node on the i2c4 bus, along with connectors for the
hdmi and cvbs inputs, and link to the csi20 and csi40 nodes as outputs.

Submitting this directly to Niklas, as these changes depend on his VIN
DT patches, and has agreed to 'take' this patch on to that series.
v4:
- dt: Rebase to dts/renesas/salvator-x.dtsi
- dt: Use AIN0-7 rather than AIN1-8
v5:
- dt: Move to salvator-common.dtsi
v6:
- remove unnecessary address-cells and size-cells configuration
- merge connectors into their respective nodes.
