crypto: blake2s - revert unintended config addition of CRYPTO_BLAKE2S

Commit 2d16803c ("crypto: blake2s - remove shash module") removes the
config CRYPTO_BLAKE2S.

Commit 3f342a23 ("crypto: Kconfig - simplify hash entries") makes
various changes to the config descriptions as part of some consolidation
and clean-up, but among all those changes, it also accidently adds back
CRYPTO_BLAKE2S after its removal due to the original patch being based on
a state before the CRYPTO_BLAKE2S removal.

See Link for the author's confirmation of this happening accidently.
