Revert "crypto: run initcalls for generic implementations earlier"

This reverts commit c4741b2305.

Crypto API self-tests no longer run at registration time and now
occur either at late_initcall or upon the first use.

Therefore the premise of the above commit no longer exists.  Revert
it and subsequent additions of subsys_initcall and arch_initcall.

Note that lib/crypto calls will stay at subsys_initcall (or rather
downgraded from arch_initcall) because they may need to occur
before Crypto API registration.
