spi: spi-rspi: Remove setting {src,dst}_{addr,addr_width} based on DMA direction

The direction field in the DMA config is deprecated. The rspi 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.

This patch fixes the issue by passing both {src,dst}_{addr,addr_width}
values independent of DMA direction.
