Subject: [PATCH 11/11] arm: dts: vexpress: describe all PMUs in TC2 dts

The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the
PMUs of the Cortex-A15 CPUs, and not the Cortex-A7 CPUs.

Now that we have a mechanism for describing disparate PMUs and their
interrupts in device tree, this patch makes use of these to describe the
PMUs for all CPUs in the system.
