Subject: [PATCH] powerpc/perf: Define perf_event_print_debug() to print PMU
 register values

Currently the sysrq ShowRegs command does not print any PMU registers as
we have an empty definition for perf_event_print_debug(). This patch
defines perf_event_print_debug() to print various PMU registers.

Example output:

CPU: 0 PMU registers, ppmu = POWER7 n_counters = 6
PMC1:  00000000 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000
PMC5:  00000000 PMC6: 00000000 PMC7: deadbeef PMC8: deadbeef
MMCR0: 0000000080000000 MMCR1: 0000000000000000 MMCRA: 0f00000001000000
SIAR:  0000000000000000 SDAR:  0000000000000000 SIER:  0000000000000000
