Correct AArch64 crypto dependencies. 

The crypto options depend on SIMD and FP, the documentation states so but the dependency is not there the code.

We have mostly gotten away with this due to the default flags
for the architectures (e.g. Armv8.2-a  implies +simd) but this
discrepancy needs to be addressed.
