Add support for protected key hmac ("phmac") for s390 arch.
With the latest machine generation there is now support for
protected key (that is a key wrapped by a master key stored
in firmware) hmac for sha2 (sha224, sha256, sha384 and sha512)
for the s390 specific CPACF instruction kmac.
This patch adds support via 4 new ahashes registered as
phmac(sha224), phmac(sha256), phmac(sha384) and phmac(sha512).

Hello Eric
with your commit
7fa481734016 crypto: ahash - make hash walk functions private to
ahash.c
you move the crypto_hash_walk_* functions to private context into
ahash.c.
So for example my new phmac does not compile any more.
What is the replacement for these functions then? Should I really do
the scatter walk by my own now or is there a set of new functions to
come?
