powerpc: Use the newly added get_required_mask dma_map_ops hook
Now that the generic code has dma_map_ops set, instead of having a
messy ifdef & if block in the base dma_get_required_mask hook push
the computation into the dma ops.
If the ops fails to set the get_required_mask hook default to the
width of dma_addr_t.
This also corrects ibmbus ibmebus_dma_supported to require a 64
bit mask. I doubt anything is checking or setting the dma mask on
that bus.
