Thomas Richter 9f66572f28 s390/pai_crypto: Enable per-task and system-wide sampling event 
The PMU for PAI crypto counters enforces the following restrictions:

      - No per-task context for PAI crypto sampling event CRYPTO_ALL
      - No multiple system-wide PAI crypto sampling event CRYPTO_ALL

Both restrictions are removed. One or more per-task sampling events
are supported. Also one or more system-wide sampling events are
supported.

Example for per-task context of sampling event CRYPTO_ALL:
       # perf record -e pai_crypto/CRYPTO_ALL/ -- true
Example for system-wide context of sampling event CRYPTO_ALL:
       # perf record -e pai_crypto/CRYPTO_ALL/ -a -- sleep 4
