drm/msm/dsi: Don't use iommu for command TX buffer for DSIv2
We currently use iommu allocated DMA buffers for sending DSI commands.
DSIv2 doesn't have a port connected to the MDP iommu. Therefore, it
can't use iommu allocated buffers to fetch DSI commands.
Use a regular contiguous DMA buffer if we are DSIv2.
