perf powerpc: Support exposing Performance Monitor Counter SPRs as part of extended regs
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.
