crypto: drbg - Remove support for HASH_DRBG
Remove the support for HASH_DRBG. It's likely unused code, seeing as
HMAC_DRBG is always enabled and prioritized over it unless
NETLINK_CRYPTO is used to change the algorithm priorities.
There's also no compelling reason to support more than one of
[HMAC_DRBG, HASH_DRBG, CTR_DRBG]. By definition, callers cannot tell
any difference in their outputs. And all are FIPS-certifiable, which is
the only point of the kernel's NIST DRBGs anyway.
Switching to HASH_DRBG doesn't seem all that compelling, either. For
one, it's more complex than HMAC_DRBG.
Thus, let's just drop HASH_DRBG support and focus on HMAC_DRBG.
