This series adds the CPG clock definitions, device node entries, and compatible
strings for the CSI-2 receivers and VIN instances on R8A779A0 R-Car V3U SoC.
The last 2 patches are under discussion, as the right way forward to support
the V3U VIN version has not yet been clarified.
Compile tested only.
