crypto: arm - use Kconfig based compiler checks for crypto opcodes

2019-10-23T08:46:56Z

Instead of allowing the Crypto Extensions algorithms to be selected when using a toolchain that does not support them, and complain about it at build time, use the information we have about the compiler to prevent them from being selected in the first place. Users that are stuck with a GCC version <4.8 are unlikely to care about these routines anyway, and it cleans up the Makefile considerably. While at it, add explicit 'armv8-a' CPU specifiers to the code that uses the 'crypto-neon-fp-armv8' FPU specifier so we don't regress Clang, which will complain about this in version 10 and later.
