Subject: [PATCH] ARM: dts: bcm2837: Enable PMU on Raspberry Pi 3

Subject: arm: bcm2835: Add the PMU to the devicetree.
This enables the PMU (performance monitoring unit) on Raspberry Pi 3.
In order to make it work on ARM and ARM64, we need to specify two
compatible strings.
This only probes on arm64 so far, but hopefully that driver will be
generalized soon.
