dm: Respect dma-ranges size
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.
