Due to the special handling of window 13 on Armada 375 and Armada 38x
(similar to Armada XP), the MBus hardware block is *not* compatible
with the one used on Armada 370. Using the Armada 370 compatible
string on Armada 375 and 38x will lead to a non-working device if
window 13 ends up being used.

Fixes: 0d3d96ab005 ("ARM: mvebu: add Device Tree description of the Armada 380/385 SoCs")
