iommu sg merging: add accessors for segment_boundary_mask in device_dma_parameters()
This adds new accessors for segment_boundary_mask in device_dma_parameters
structure in the same way I did for max_segment_size. So we can easily change
where to place struct device_dma_parameters in the future.
dma_get_segment boundary returns 0xffffffff if dma_parms in struct device
isn't set up properly. 0xffffffff is the default value used in the block
layer and the scsi mid layer.
