perf/x86/intel/uncore: Add domain global init callback
In the Intel uncore self-describing mechanism, the Global Control
Register freeze_all bit is SoC-wide and propagates to all uncore PMUs.
On Diamond Rapids, this bit is set at power-on, unlike some prior
platforms. Add a global_init callback to unfreeze all PMON units.
