crypto: ansi_cprng - Remove unused ansi_cprng algorithm
Remove ansi_cprng, since it's obsolete and unused, as confirmed at https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/ This was originally added in 2008, apparently as a FIPS approved random number generator. Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around.
