arm64: dts: renesas: r8a779a0: Update to R-Car Gen4 compatible values

Despite the name, R-Car V3U is the first member of the R-Car Gen4
family.  Hence update the compatible properties in various device nodes
to include family-specific compatible values for R-Car Gen4 instead of
R-Car Gen3:
  - CMT,
  - SDHI.
