s390/pai_crypto: Add common pai_add() function

Browse Source 
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.

Add a common usable function pai_add() for the event on a CPU.
Call this common pai_add() from paicrypt_add().
