powerpc/perf: Add a shared interface to get gpci version and capabilities This exposes a simple way to grab the firmware provided collect_priveliged, ga, expanded, and lab capability bits. All of these bits come in from the same gpci request, so we've exposed all of them. Only the collect_priveliged bit is really used by the hv-gpci/hv-24x7 code, the other bits are simply exposed in sysfs to inform the user.
