To enable presenting of Performance Monitor Counter Registers (PMC1 to PMC6) as part of extended regsiters, this patch adds these to sample_reg_mask in the tool side (to use with -I? option). Simplified the PERF_REG_PMU_MASK_300/31 definition. Excluded the unsupported SPRs (MMCR3, SIER2, SIER3) from extended mask value for CPU_FTR_ARCH_300.
