perf list: Fix PMU name pai_crypto in perf list on s390
Commit e0b23af82d6f454c ("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] ...
