The direction field in the DMA config is deprecated. The sh-sci driver
sets {src,dst}_{addr,addr_width} based on the DMA direction and
it results in dmaengine_slave_config() failure as RZ DMAC driver
validates {src,dst}_addr_width values independent of DMA direction.
Fix this issue by passing both {src,dst}_{addr,addr_width}
values independent of DMA direction.
