[S390] move crypto options and some cleanup.
This patch moves the config options for the s390 crypto instructions to the standard "Hardware crypto devices" menu. In addition some cleanup has been done: use a flag for supported keylengths, add a warning about machien limitation, return ENOTSUPP in case the hardware has no support, remove superfluous printks and update email addresses.

+ help
+ This is the s390 hardware accelerated implementation of the

+
+ This version of SHA implements a 256 bit hash with 128 bits of
+ security against collision attacks.

+ tristate "AES cipher algorithms"
+ depends on S390
+ select CRYPTO_ALGAPI
+ select CRYPTO_BLKCIPHER
+ help
+ This is the s390 hardware accelerated implementation of the
+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.
+
+ On s390 the System z9-109 currently only supports the key size
+ of 128 bit.
+
+config S390_PRNG
+ tristate "Pseudo random number generator device driver"
+ depends on S390
+ default "m"
+ help
+ Select this option if you want to use the s390 pseudo random number
+ generator. The PRNG is part of the cryptograhic processor functions
+ and uses triple-DES to generate secure random numbers like the
+ ANSI X9.17 standard. The PRNG is usable via the char device
+ /dev/prandom.
