s390/crypt: Add protected key AES module
This patch introduces a new in-kernel-crypto blockcipher
called 'paes' which implements AES with protected keys.
The paes blockcipher can be used similar to the aes
blockcipher but uses secure key material to derive the
working protected key and so offers an encryption
implementation where never a clear key value is exposed
in memory.
The paes module is only available for the s390 platform
providing a minimal hardware support of CPACF enabled
with at least MSA level 3. Upon module initialization
these requirements are checked.
Includes additional contribution from Harald Freudenberger.
