perf/x86/intel/uncore: Defer ADL global PMON enable to enable_box()
On some Raptor Cove CPUs, enabling uncore PMON globally at driver init
may increase power consumption even when no perf events are in use.
Drop adl_uncore_msr_init_box() and defer programming the global control
register to enable_box(), so it is only set when a box is actually used.
IMC and IMC freerunning counters use a separate control path and are
unaffected.
