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.
