Christoph Hellwig fc0021aa34 swiotlb: remove the tbl_dma_addr argument to swiotlb_tbl_map_single 
The tbl_dma_addr argument is used to check the DMA boundary for the
allocations, and thus needs to be a dma_addr_t.  swiotlb-xen instead
passed a physical address, which could lead to incorrect results for
strange offsets.  Fix this by removing the parameter entirely and hard
code the DMA address for io_tlb_start instead.
