The build issue can be solved by
-#include <linux/dma-iommu.h>
+#include <linux/dma-mapping.h>
+#include <linux/iommu.h>

Since CONFIG_IOMMU_DMA is not defined in the arch.
include/linux/dma-iommu.h
#ifdef CONFIG_IOMMU_DMA
#include <linux/dma-mapping.h>
#include <linux/iommu.h>

Will update later.

Thanks
