Milton Miller d24f9c6999 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.
