Use the dma_set_mask_and_coherent helper to set vdec DMA bit mask to support 34bits iova space(16GB) that the mt8192 iommu HW support.
Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G, regarding which iova range VDEC actually locate, it depends on the dma-ranges property of vdec dtsi node.
