ARM: perf: register CPU PMUs with idr types
In order to support multiple, heterogeneous CPU PMUs and distinguish
them, they cannot be registered as PERF_TYPE_RAW type. Instead we can
get perf core to allocate a new idr type id for each PMU.
Userspace applications can refer sysfs entried to find a PMU's type,
which can then be used in tracking events on individual PMUs.
