The main advantage I can see for going fully dynamic is that we can use
a larger aperture and more windows for PCIe on systems that don't use
all of the other windows from the ${SOC}.dtsi file. If we don't have
a NAND chip connected, the ${BOARD}.dts file can easily mark the nand
controller node as status="disabled" and we don't have to give it a
physical address.

It's not a strong reason, but I think it's nice and clean to assign
the windows automatically and exactly for the hardware that we are
going to use.
