Subject: [PATCH v1] perf vendor events intel: Add umasks to PCU events.
UMasks were being dropped leading to all PCU
UNC_P_POWER_STATE_OCCUPANCY events having the same encoding. Don't
drop the umask trying to be consistent with other sources of events
like libpfm4 [1]. This applies the change from [2].

[2] https://github.com/captain5050/perfmon/commit/661a229996493448095fb55415ed568ceabc631b
