ARM: perf: allow armpmu to implement mode exclusion
Modern PMUs allow for mode exclusion, so we no longer wish to return
-EPERM if it is requested.
This patch provides a hook in the armpmu structure for implementing
mode exclusion. The hw_perf_event initialisation is slightly delayed so
that the backend code can update the structure if required.
