Not easily.  As we discussed before, there is nowhere that really
specifies this information.  In some cases I've modified the device tree
generator to understand what is backward compatible, as with ns16550,
but for other cores it makes more sense to me to put this compatibility
information with the driver if it has to be anywhere.
