perf/x86/intel/uncore: Factor out box setup code

The PCI uncore PMU path already implements a lazy registration model:
the PMU is registered when the first active box appears and
unregistered when the last active box is removed.

Factor this registration management into a shared helper, so the same
code can be reused by the MSR and MMIO paths in later changes.

No functional change intended.
