Use 'dma-coherent-hint-cached' instead of 'dma-coherent' for the fastrpc iommu context banks. Now, on a QGKI kernel, cached ION buffers will be DMA mapped as IOMMU cached for the fastrpc devices, all other buffers will be DMA mapped as IOMMU uncached and dma_alloc_attrs will always return memory with a cached CPU mapping as well as DMA mapping its memory as IOMMU cached. On a GKI kernel, all buffers for fastrpc devices will be DMA mapped as IOMMU uncached and dma_alloc_attrs will always return CPU uncached memory.
