perf/x86/intel/uncore: Add Lunar Lake support

Browse source

The uncore subsystem for Lunar Lake is similar to the previous
Meteor Lake. The uncore PerfMon registers are located at both
MSR and MMIO space.

The ARB and iMC are kept. There is no difference from the Meteor Lake.
Move the global control initialization to the first box of the CBOX.

The sNCU is moved to the MMIO space.

The HBO is newly added and only be accessed from the MMIO space.
