Kan Liang a5a6ff3d63 perf/x86/intel/uncore: Fix the bits of the CHA extended umask for SPR 
The perf stat errors out with UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL
event.

 $perf stat -e uncore_cha_55/event=0x35,umask=0x10c0008101/ -a -- ls
    event syntax error: '..0x35,umask=0x10c0008101/'
                                      \___ Bad event or PMU

The definition of the CHA umask is config:8-15,32-55, which is 32bit.
However, the umask of the event is bigger than 32bit.
This is an error in the original uncore spec.

Add a new umask_ext5 for the new CHA umask range.

Fixes: 949b11381f ("perf/x86/intel/uncore: Add Sapphire Rapids server CHA support")
