This depends on what the hardware does and how the device is registered
- if the device is registered with an ID provided (which you can do)
then AMBA won't bother reading the ID back and verifying that it's
correct so there's no interaction with the hardware until we hit the
driver.

I've not checked the DT case, though it doesn't seem like there's any
check that the compatible string matches the ID read from the hardware
which is a bit interesting...
