[S390] zcrypt driver Makefile, Kconfig and monolithic build.



The Makefile and Kconfig changes should be obvious. The monolithic
build option is there to create an old-style z90crypt module for
backward compatability to older distributions.

Select this option if you want to use a PCI-attached cryptographic
adapter like:
+ PCI Cryptographic Accelerator (PCICA)
+ PCI Cryptographic Coprocessor (PCICC)
+ PCI-X Cryptographic Coprocessor (PCIXCC)
+ Crypto Express2 Coprocessor (CEX2C)

Select this option if you want to have a single module z90crypt.ko
that contains all parts of the crypto device driver (ap bus,
request router and all the card drivers).
