Eric Biggers b59059a22c lib/crypto: riscv/sha512: Migrate optimized SHA-512 code to library
Instead of exposing the riscv-optimized SHA-512 code via riscv-specific
crypto_shash algorithms, instead just implement the sha512_blocks()
library function.  This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be riscv-optimized, and it fixes the
longstanding issue where the riscv-optimized SHA-512 code was disabled
by default.  SHA-512 still remains available through crypto_shash, but
individual architectures no longer need to handle it.

To match sha512_blocks(), change the type of the nblocks parameter of
the assembly function from int to size_t.  The assembly function
actually already treated it as size_t.

Note: to see the diff from arch/riscv/crypto/sha512-riscv64-glue.c to
lib/crypto/riscv/sha512.h, view this commit with 'git show -M10'.
