lib/crypto: s390/ghash: Migrate optimized code into library

Browse source

Remove the "ghash-s390" crypto_shash algorithm, and replace it with an
implementation of ghash_blocks_arch() for the GHASH library.

This makes the GHASH library be optimized with CPACF.  It also greatly
reduces the amount of s390-specific glue code that is needed, and it
fixes the issue where this GHASH optimization was disabled by default.
