And in addition to using ranges, please set up separate bus instances
for the interconnects. This will then allow you to probe WKUP or
similar instance first and the other bus instances after. And that
pretty much allows you to get rid of the annoying -EPROBE_DEFER
ping pong and allows making clocks proper device drivers ;)
