Ard Biesheuvel c1047edeb3 arm64/crypto: use crypto instructions to generate AES key schedule

(cherry pick from commit 12ac3efe74f888a13cb4df88b38bb01e8034dea8)

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.
