aarch64/arm: Add compiler barrier to barrier instructions

When issuing barrier instructions like DSB or DMB, we must make sure
that the compiler does not undermine out efforts to fence off
instructions. Currently the compiler is free to move the barrier
instruction around, in respect to former or later memory access
statements, which is not what we want.

Add a compiler barrier to the inline assembly statement in our
DEFINE_SYSOP_TYPE_FUNC macro, to make sure memory accesses are not
reordered by the compiler.
This is in line with Linux' definition:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/include/asm/barrier.h

Since those instructions share a definition, apart from DSB and DMB this
now also covers some TLBI instructions. Having a compiler barrier there
also is useful, although we probably have stronger barriers in place
already.
