(cherry picked from commit 69369f52d28a34c84acb6f2a8a585e743441566a)
on 8QM A0, video play use ion to allocate buffer and mmap buffer,
there is a call dma_get_sgtable, but xen arm not implement that.
when playing video, GPU driver will use sg dma address, but because
of xen_swiotlb_get_sgtable not implemented, sg->amd_address is not
exactly the address that ion allocated. This patch fixes the issue.
