If each bus interface has a fixed range of registers, you can actually
collapse the upper two nodes again and just have one device per
chipselect.

This is indeed the case, but I'd rather keep the top node to highlight
the fact that all the devices are physically tied to the same bus.

How about using a top-level "simple-bus" node with the complex ranges
property but making the driver match the sub-devices with the smaller
register range then?
