Brian Behlendorf 84dd55510b zstd: disable intrinsics
Disable the aarch64 NEON SIMD intrinsics for kernel builds.  Safely
using them in the kernel context requires saving/restoring the FPU
registers which is not currently done.

Additionally, remove the aarch64 optimized PREFETCH_L1 and PREFETCH_L2
instruction.  Rely on the more portable compiler built ins.

This lets us remove the problematic workaround in the aarch64_compat.h
header which undefines the __aarch64__ macro.
