Revert "perf list: Add s390 support for detailed/verbose PMU event description"
This reverts commit 038586c34301578e538f6c5aa79ca82bce1b9152.
Fix the support of detailed/verbose PMU event description by using the
"Unit": keyword in the json files to address event names refering to the
/sys/devices/cpum_[cs]f devices.
