Revert "[media] V4L: videobuf, don't use dma addr as physical"
This reverts commit 35d9f510b67b10338161aba6229d4f55b4000f5b.
Quoth Jiri Slaby:
"It fixes mmap when IOMMU is used on x86 only, but breaks architectures
like ARM or PPC where virt_to_phys(dma_alloc_coherent) doesn't work.
We need there dma_mmap_coherent or similar (the trickery what
snd_pcm_default_mmap does but in some saner way). But this cannot be
done at this phase."
