media: mediatek: vcodec: Remove the setting for dma_mask

Browse Source 
In order to simplify the masters to set their respective dma masks, MTK
IOMMU helps to centralize the processing. Because all the dma ranges is
set in IOMMU, IOMMU knows well the dma mask requirements of masters. After
this patch, the masters(codec here) code does not need care
dma-ranges/dma_mask related information.
