perf: Power7: Make CPI stack events available in sysfs

A set of Power7 events are often used for Cycles Per Instruction (CPI) stack
analysis. Make these events available in sysfs (/sys/devices/cpu/events/) so
they can be identified using their symbolic names:

	perf stat -e 'cpu/PM_CMPLU_STALL_DCACHE_MISS/' /bin/ls
