This is a platform-specific bus (PXA27x). Should it go into pxa27x.dtsi
rather than machine dts?

There seems to be none at the moment. However, some machines need to
setup these partitions as a part of their initialization. So complete
migration to DT will require this driver.

In LP-8x4x case everything is setup by the bootloader. So "simple-bus"
works for me.
