AArch64: remove SM4 support from Apple CPUs.

The CPUs never supported SM4 instructions, but until recently I think crypto
was folded into the baseline architecture as a monolithic feature so it was
difficult to represent that. Now it's split we can, and the CPUs that support
v8.4 onwards only handle AES, SHA2, SHA3 by way of crypto instructions.
