s390/zcrypt: remove CEX2 and CEX3 device drivers
Remove the legacy device driver code for CEX2 and CEX3 cards. The last machines which are able to handle CEX2 crypto cards are z10 EC first available 2008 and z10 BC first available 2009. The last machines able to handle a CEX3 crypto card are z196 first available 2010 and z114 first available 2011. Please note that this does not imply to drop CEX2 and CEX3 support in general. With older kernels on hardware up to the aforementioned machine models these crypto cards will get support by IBM. The removal of the CEX2 and CEX3 device drivers code opens up some simplifications, for example support for crypto cards without rng support can be removed also.
