Some cleanup in the s390 zcrypt device driver:
- Removed fragments of pcixx crypto card code. This code
can't be reached anymore because the hardware detection
function does not recognize crypto cards < CEX2 since
commit f56545430736 ("s390/zcrypt: Introduce QACT support
for AP bus devices.")
- Rename of some files and driver names which where still
reflecting pcixx support to cex2a/cex2c.
- Removed all the zcrypt version strings in the file headers.
There is only one place left - the zcrypt.h header file is
now the only place for zcrypt device driver version info.
- Zcrypt version pump up from 2.2.0 to 2.2.1.
