This series introduces a partial block helper for lib/crypto hash
algorithms based on the one from sha256_base.

It then uses it on poly1305 to eliminate duplication between
architectures.  In particular, instead of having complete update
functions for each architecture, reduce it to a block function
per architecture instead.  The partial block handling is handled
by the generic library layer.

The poly1305 implementation was anomalous due to the inability
to call setkey in softirq.  This has since been resolved with
the addition of cloning.  Add setkey to poly1305 and switch the
IPsec code (rfc7539) to use that.

Finally add a partial blocks conversion for polyval.
