Changes from v13: * Rename cp15.h to sysreg.h for ARMv7 and add a new file sysreg.h for ARMv8 * Add macros for read_sysreg() and write_sysreg(). CP15 registers can be defined with __ACCESS_CP15() or __ACCESS_CP15_64(). sysreg.h (ARMv8) was from Drew's GIC testing code, which can be leveraged when his GIC testing code is imported. * Rewrite PMU testing code based on new macros. All get_xxx() and set_xxx() functions are defined in pmu.c based on read_sysreg() and write_sysreg(). So the code parsing tool, like cscope, can parse them easily. * Minor fixes inside pmu.c, printf formatting, pmu_probe() func, based on Andre's comments.
Note: 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.
