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. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
