crypto: x86/sha1 - autoload if SHA-NI detected
The x86 SHA-1 module contains four implementations: SSSE3, AVX, AVX2,
and SHA-NI. Commit 1c43c0f1f84a ("crypto: x86/sha - load modules based
on CPU features") made the module be autoloaded when SSSE3, AVX, or AVX2
is detected. The omission of SHA-NI appears to be an oversight, perhaps
because of the outdated file-level comment. This patch fixes this,
though in practice this makes no difference because SSSE3 is a subset of
the other three features anyway. Indeed, sha1_ni_transform() executes
SSSE3 instructions such as pshufb.
