My main concern here is that this creates an inconsistency in the device 
tree representation that only works because PCI drivers happen not to 
use these code paths. Logically, having "nonposted-mmio" above the PCI 
controller would imply that it applies to that bus too. Sure, it doesn't 
matter for Linux since it is ignored, but this creates an implicit 
exception that PCI buses always use posted modes.

Then if a device comes along that due to some twisted fabric logic needs 
nonposted nGnRnE mappings for PCIe (even though the actual PCIe ops will 
end up posted at the bus anyway)... how do we represent that? Declare 
that another "nonposted-mmio" on the PCIe bus means "no, really, use 
nonposted mmio for this"?
