Changes from v12: * Define macros for system register accessors * Re-write PMU code using the newly-defined macros * Code tested under both AArch32 and AArch64 modes
Note: 1) Current KVM code has bugs in handling PMCCFILTR write. A fix (see below) is required for this unit testing code to work correctly under KVM mode. https://lists.cs.columbia.edu/pipermail/kvmarm/2016-November/022134.html.
