media: imx: imx7-media-csi: Rename phys variables to dma_addr
All the phys variables and structure fields store a DMA address, not a
physical address. Even if the two are effectively identical on all
platforms where this driver is used due to the lack of IOMMU, rename the
variables to dma_addr to make their usage clearer.
