DTB: Translate MMIO addresses through nested buses
...
The existing MMIO helper only translates addresses through the /soc
ranges property. This does not handle devices below nested buses,
such as the UART in the devicetree used by the Meson boards.
Add an address translator that walks each ancestor bus and applies
its ranges property until reaching the CPU address space. Treat
empty ranges as an identity mapping and reject regions that cross a
range boundary.
Keep the existing helper’s behavior unchanged for other devices to
limit the scope of the behavioral change.
Add tests for nested buses, empty ranges, exact range boundaries,
and regions crossing a boundary.
