arm64: dts: renesas: Add R8A779G0 V4H remoteproc DT node

Describe APMU controller as a remoteproc device capable of starting
the Cortex-R52 cores in Renesas R8A779G0 V4H SoC DT. The APMU IP is
in fact a power management unit capable of additional operations, but
those are not used by U-Boot so far.
