perf/x86/intel/uncore: Add Panther Lake support
The Panther Lake supports CBOX, MC, sNCU, and HBO uncore PMON.
The CBOX is similar to Lunar Lake. The only difference is the number of
CBOX.
The other three uncore PMON can be retrieved from the discovery table.
The global control register resides in the sNCU. The global freeze bit
is set by default. It must be cleared before monitoring any uncore
counters.
