powerpc/perf: factor out power8 __init_pmu code



Factor out the power8 pmu init functions to share with
power9. Monitor Mode Control Register S(MMCRS) and
Monitor Mode Control Register H(MMCRH) registers are
dropped in Power9. These registers are added to new
function which are included for power8 init.
