s390/pai_crypto: Rename paicrypt_getdata() to pai_getdata()

To support one common PAI PMU device driver which handles
both PMUs pai_crypto and pai_ext, use a common naming scheme
for structures and variables suitable for both device drivers.
Rename paicrypt_getdata() to pai_getdata(). Use the PAI PMU
characteristics in the pai_pmu table to determine the number
of counters to be extracted.
