[PATCH v2 2/2] arm64: dts: renesas: r8a77970: Add Cortex-A53 PMU node

[Geert Uytterhoeven]

Enable the performance monitor unit for the Cortex-A53 cores on the
R-Car V3M (r8a77970) SoC.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

v2:
  - Move the pmu node from the soc subnode to the root node, as it
    doesn't have registers.
