arm64: dts: renesas: r8a779a0: Add family fallback for CSISP IP

To make it easier to support new R-Car Gen4 SoCs add a family fallback
compatible similar to what was done for VIN on R-Car Gen4.

There is no functional change, but the addition of the family fallback
in the bindings produces warnings for R-Car V3U for DTS checks if they
are not added.
