The Armada 375, like the Armada 370 and Armada XP, has a coherency unit. However, unlike the coherency unit of 370/XP which does both CPU and I/O coherency, the one on Armada 735 only does I/O coherency. Therefore, instead of having two sets of registers (the first one being used mainly to register each CPU in the coherency fabric, the second one being used for the I/O coherency barrier), it has only one set of register (for the I/O coherency barrier). This commit adds a new "marvell,armada-375-coherency-fabric" compatible string for this variant of the coherency fabric. The custom DMA operations, and the way of triggering an I/O barrier is the same as Armada 370/XP, so the code changes are minimal. However, the set_cpu_coherent() function is not needed on Armada 375 and will not work.
