We have to enable this flag to support dynamically adding devices to the
sysbus. This change is needed for the the upcoming diag288 watchdog.
s390 doesn't have a "sysbus" per se. Please create a new bus type.
So what's wrong with the sysbus? I don't see why we should be different
than everyone else.
The idea behind sysbus is that you have MMIO, PIO and IRQ pins
connecting to a PIC. It provides a lot of infrastructure for those
interfaces. S390 doesn't use any of them and instead wants registration
on "diag" interfaces for example which I'd put on the same layer as PIO
or MMIO registration.
