Subject: [PATCH] dm: Introduce dev_phys_to_bus()/dev_bus_to_phys()
These functions, instead of relying on hard-coded platform-specific
address translations, make use of the DMA constraints provided by the DM
core. This allows for per-device translations.
We can't yet get rid of the legacy phys_to_bus()/bus_to_phys()
implementations as some of its users are not integrated into the
device model.
