Commit 2c54b423cf85 ("arm64/xor: use EOR3 instructions when available")
changes the definition to __ro_after_init instead of const, but failed to
update the external declaration in xor.h. This was not found because
xor-neon.c doesn't include <asm/xor.h>, and can't easily do that due to
current architecture of the XOR code.
