Rework dev_phys_to_bus() and dev_bus_to_phys() to respect the size
of the area specified in dma-ranges DT property. The area outside
of ranges is remapped 1:1, while the area in the ranges is remapped
according to the description in the dma-ranges property.
Adjust the test to test the area within the remapped range, not area
outside the remapped range, which was incorrect.

Not a big expert, but this looks good to me:

This was broken long enough, so this should go into next so it would get
sufficient testing before the next release.

Ah thanks, yes, the macro had the check for DM_DMA, I missed that.
