Otherwise we will end up where bindings/arm/primecell.yaml is: hardware ID numbers that were supposed to be updated but weren't, so now both DT and the kernel has to go through all kinds of loops and hoops to make it work by encoding the number that should have been in the hardware is instead in the device tree...
