Calls into the skcipher API can only occur from contexts where the SIMD
unit is available, so there is no need for the SIMD helper.

It would be helpful if the commit message made it clear that "Calls into the
skcipher API can only occur from contexts where the SIMD unit is available" is
something that is now the case but wasn't the case previously.  Otherwise I
could see people backporting this patch without its prerequisites.

Likewise for some of the other patches in this patchset.
OK
