ARM: mvebu: Relocate Armada 370/XP DeviceBus device tree nodes
Browse files Browse the repository at this point in the history 
Now that mbus has been added to the device tree, it's possible to
move the DeviceBus out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the hardware.
