ARM: 5903/1: arm/perfevents: add support for ARMv7
Adds the Performance Events support for ARMv7 processor, using
the PMNC unit in HW.
Supports the following:
- Cortex-A8 and Cortex-A9 processors,
- dynamic detection of the number of available counters,
based on the PMCR value,
- runtime detection of the CPU arch (v6 or v7)
and model (Cortex-A8 or Cortex-A9)
Tested on OMAP3 (Cortex-A8) only.
