[PATCH] dt-bindings: mmc: arasan,sdhci: Allow "dma-coherent" property

[Rob Herring (Arm)]

The Arasan SDHCI controller is DMA coherent on the APM merlin SoC, so allow
the dma-coherent property. No reason implementations can't also be coherent
and there's not an SoC specific compatible, so allow it on any platform.
