perf/x86/amd/uncore: Refactor uncore management
Since struct amd_uncore is used to manage per-cpu contexts, rename it to
amd_uncore_ctx in order to better reflect its purpose. Add a new struct
amd_uncore_pmu to encapsulate all attributes which are shared by per-cpu
contexts for a corresponding PMU. These include the number of counters,
active mask, MSR and RDPMC base addresses, etc. Since the struct pmu is
now embedded, the corresponding amd_uncore_pmu for a given event can be
found by simply using container_of().
Finally, move all PMU-specific code to separate functions. While the
original event management functions continue to provide the base
functionality, all PMU-specific quirks and customizations are applied in
separate functions.
The motivation is to simplify the management of uncore PMUs.
