xen_dma_sync_for_cpu, xen_dma_sync_for_device, xen_arch_need_swiotlb are getting called passing dma addresses. On some platforms dma addresses could be different from physical addresses. Before doing any operations on these addresses we need to convert them back to physical addresses using dma_to_phys. Move the arch_sync_dma_for_cpu and arch_sync_dma_for_device calls from xen_dma_sync_for_cpu/device to swiotlb-xen.c, and add a call dma_to_phys to do address translations there. dma_cache_maint is fixed by the next patch.
