I've just replaced the of_iomap() call with an open coded version,
calling of_address_to_resource() and ioremap() directly. That was
needed so I can use the struct resource returned by
of_address_to_resource() to set the syscon_config.max_register. I
don't see where this could cause resource overlap. Does just setting
syscon_config.max_register to zero again make the problem disappear?

Yes commenting out the syscon_config.max_register line in your patch
makes things work again.

So what does that tell us about the problem?
