[PATCH 3/7 v2] powerpc/dma: implement per-platform dma_get_page_shift
The IOMMU page size is not always stored in struct iommu on Power. Specifically if a device is configured for DDW (Dynamic DMA Windows aka. 64-bit direct DMA), the used TCE (Translation Control Entry)...

We received a bug report recently when DDW (64-bit direct DMA on Power) is not enabled for NVMe devices. In that case, we fall back to 32-bit DMA via the IOMMU, which is always done via 4K TCEs...
