Subject: [PATCH v2] lib/crypto: add prompts back to crypto libraries

Commit 6048fdcc5f269 ("lib/crypto: blake2s: include as built-in") took
away a number of prompt texts from other crypto libraries. This makes
values flip from built-in to module when oldconfig runs, and causes
problems when these crypto libs need to be built in for thingslike
BIG_KEYS.

Fixes: 6048fdcc5f269 ("lib/crypto: blake2s: include as built-in")
