serial: sh-sci: Kill off some DMA ifdeffery.
There's nothing worth hiding under the ifdef in the platform DMA definitions, and we certainly don't want board code adding this in to their platform data definitions, so we always expose the slave rx/tx and device pointer members instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
