soc: rockchip: power-domain: Replace dsb() with smb()
It's unclear if these are really needed at all, but seemingly their
purpose is only as a write barrier. Use the general macro instead of the
ARM-specific one.
This driver is partially marked for COMPILE_TEST'ing, but it doesn't
build under non-ARM architectures. Fix this up before *really* enabling
it for COMPILE_TEST.
