This will fail the compile test, because dsb() is not available on non-ARM
architectures. Would it be enough to just use the normal writel() accessor
here?

That's a good question and I believe we can remove it but I have to setup a rockchip board before doing the changes in order to test.

I the meantime added the COMPILE_TEST option but restricted it to ARM and ARM64.
