ARM: 5902/4: arm/perfevents: implement perf event support for ARMv6
This patch implements support for ARMv6 performance counters in the Linux performance events subsystem. ARMv6 architectures that have the performance counters should enable HW_PERF_EVENTS to get hardware performance events support in addition to the software events. Note: only ARM Ltd ARM cores are supported. This implementation also provides an ARM PMU abstraction layer to allow ARMv7 and others to be supported in the future by adding new a 'struct arm_pmu'.
