Rob Herring 1dc737c44a ARM: highbank: add coherent DMA setup
Some highbank DMA masters can support coherent (ACP) or non-coherent DMA.
This sets up dma_map_ops for masters which are configured for coherent DMA.

* Calxeda Highbank 10Gb XGMAC Ethernet
Required properties:
- compatible : Should be "calxeda,hb-xgmac"
- reg : Address and length of the register set for the device
- interrupts : Should contain 3 xgmac interrupts. The 1st is main interrupt.
The 2nd is pwr mgt interrupt. The 3rd is low power state interrupt.
Optional properties:
- dma-coherent : Present if dma operations are coherent
Example:
ethernet@fff50000 {
compatible = "calxeda,hb-xgmac";
reg = <0xfff50000 0x1000>;
interrupts = <0 77 4 0 78 4 0 79 4>;
};
