[5.10,0/4] Fix built-in testing dependency failures

Message

When complex algorithms that depend on other algorithms are built
into the kernel, the order of registration must be done such that
the underlying algorithms are ready before the ones on top are
registered. As otherwise they would fail during the self-test
which is required during registration.

We can enable fips=1 and ecdh, the calltrace like below:

alg: ecdh: test failed on vector 2, err=-14
Kernel panic - not syncing: alg: self-tests for ecdh-generic (ecdh)
failed in fips mode!

adad556efcd ("crypto: api - Fix built-in testing dependency failures") will
fix the issue, and others fix its bugs.

So we can merge them into linux-5.10-y to fix it, thanks!
