Subject: [PATCH 1/4] 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.
