s390x: Add hardware acceleration for HMAC
The CPACF instruction KMAC provides support for accelerating the HMAC
algorithm on newer machines for HMAC with SHA-224, SHA-256, SHA-384, and
SHA-512.
Preliminary measurements showed performance improvements of up to a factor
of 2, dependent on the message size, whether chunking is used and the size
of the chunks.
