Patch set to add support for perf extended register capability in
powerpc. The capability flag PERF_PMU_CAP_EXTENDED_REGS, is used to
indicate the PMU which support extended registers. The generic code
define the mask of extended registers as 0 for non supported architectures.

patch 1/2 defines the PERF_PMU_CAP_EXTENDED_REGS mask to output the
values of mmcr0,mmcr1,mmcr2 for POWER9. Defines `PERF_REG_EXTENDED_MASK`
at runtime which contains mask value of the supported registers under
extended regs.

Applied to powerpc/fixes.
