Need to be able to pass additional DMA constraints, e.g. a 32-bit only PCI device may be used in a system that's otherwise capable of 64-bit DMA.
The simple way is to just to make this a bitfield attribute. It should only be necessary to support PCI devices on RCs described with DT. Everything else should be describe-able in DT.
