ARM: dts: imx7: add CPU PMU support



Enable support for ARM Performance Monitoring Units available
on the Cortex-A7 CPU. There is only a single interrupt for the
PMU in both variants of the family, i.MX 7Solo and 7Dual.

Tested with perf on a i.MX 7Dual:
  hw perfevents: enabled with armv7_cortex_a7 PMU driver, 5 counters available
