There is no real technical need to use the extended one, but it is
more concise. That's why we just converted all such cases in Renesas
DTS files in v6.13-rc1.

And of course it reduces the difference between
arch/arm64/boot/dts/renesas/white-hawk-cpu-common.dtsi and
arch/arm64/boot/dts/renesas/r8a779h0-gray-hawk-single.dts.

when I'm talking to journalists I just say "programmer" or something like that.
