media: rcar-csi2: Prepare for C-PHY support
Gen4 will support both D-PHY and C-PHY, while Gen3 only supports D-PHY.
Add two flags to the device information structure to be able to record
what each SoC supports.
Extend the device node parsing to accept both CSI_2 D-PHY and C-PHY
buses, while at the same time taking the SoC support into account.
