[PATCH] perf/x86/intel/uncore: Fix the lack of ch_mask format for SPR

[Jing Zhang]

perf stat errors out with UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL event
because of lack of ch_mask format in drivers, and perf test "104: perf
all PMU test (exclusive)" failed.

$perf stat -e perf stat -e UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL
sleep 1

Initial error:
event syntax error: 'UNC_CHA_TOR_INSERTS.IA_HIT_CXL_ACC_LOCAL'
                                \___ unknown term 'ch_mask' for pmu 'uncore_cha_0'

104: perf all PMU test (exclusive)                                   : FAILED!

Add ch_mask format for SPR to fix it.
