This patch implements the AES key schedule generation using ARMv8
Crypto Instructions. It replaces the table based C implementation
in aes_generic.ko, which means we can drop the dependency on that
module.

I don't really understand the AES stuff but there's something else I
noticed: if you build a kernel with the crypto stuff and run it on an
implementation that does not have the crypto extensions, there does not
seem to be any check for not using these algorithms (or falling back to
the generic implementation). Does the kernel end up with undef faults?
