[PATCH 6/8] crypto: aegis128 - Use neon-intrinsics.h on ARM too

[Josh Law]

Hi ard, this is a good cleanup!

Being able to drop <arm_neon.h> and just using
<asm/neon-intrinsics.h> across both architectures makes the C code much
cleaner.

-# Enable <arm_neon.h>
-CFLAGS_aegis128-neon-inner.o += -isystem $(shell $(CC) -print-file-name=include)

Getting rid of the isystem is good. iirc that was a hack anyway, feel free
to correct me on that
