crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3 implementation to base layer
This removes all the boilerplate from the existing implementation, and replaces it with calls into the base layer. It also changes the prototypes of the core asm functions to be compatible with the base prototype void (sha512_block_fn)(struct sha256_state *sst, u8 const *src, int blocks) so that they can be passed to the base layer directly.
