#     powerpc/perf: Add extended regs support for power10 platform
#     
#     Include capability flag PERF_PMU_CAP_EXTENDED_REGS for power10 and
#     expose MMCR3, SIER2, SIER3 registers as part of extended regs. Also
#     introduce PERF_REG_PMU_MASK_31 to define extended mask value at
#     runtime for power10.
