crypto: Clean up help text for CRYPTO_SHA256



NFS, Ceph, SMB, and Btrfs stopped using this SHA-256 implementation in
commits c2c90a8b ("nfsd: use SHA-256 library API instead of
crypto_shash API"), 27c0a7b0 ("libceph: Use HMAC-SHA256 library
instead of crypto_shash"), 924067ef ("ksmbd: Use HMAC-SHA256
library for message signing and key generation"), and fe11ac19
("btrfs: switch to library APIs for checksums").
