  commit e0b23af82d6f4 ("perf list: Add PMU pai_crypto event description for IBM z16")
introduced the Processor Activity Instrumentation for cryptographic
counters for z16. The PMU device driver exports the counters via sysfs
files listed in directory /sys/devices/pai_crypto.

To specify an event from that PMU, use perf stat -e pai_crypto/XXX/

However the json file mentioned in above commit exports the counter
decriptions in file pmu-events/arch/s390/cf_z16/pai.json.
Rename this file to pmu-events/arch/s390/cf_z16/pai_crypto.json
to make the naming consistent.

Now perf list shows the counter names under pai_crypto section:
pai_crypto:
  CRYPTO_ALL
       [CRYPTO ALL. Unit: pai_crypto]
  ....

Output before was
pai:
  CRYPTO_ALL
       [CRYPTO ALL. Unit: pai_crypto]
  ....

Thanks, applied.
