[PATCH 4/5] ARM64: dts: marvell: armada37xx: Wire PMUv3

[Marc Zyngier]

The Cortex-A53s that power the Armada-37xx SoCs are equipped with
a PMUv3, just like most ARMv8 cores.

Advertise the PMUv3 presence in the device tree, and wire its
interrupt. This allows the perf subsystem to work correctly.
