[PATCH v2] media: dt-bindings: media: renesas,vin: Add r8a779a0 support

[Niklas Söderlund]

Document support for the VIN module in the Renesas V3U (r8a779a0) SoC.
The V3U is different from other SoCs as it have 32 instead of 8 (most of
Gen3) or 16 (V3H) VIN instances. The VIN instances are also connected to
a new IP the R-Car ISP Channel Selector.
