[PATCH] dma: pxa_dma: don't use config direction parameter

[Robert Jarzmik]

From: Robert Jarzmik <rj at valbob.noip.me>

Don't use the direction passed in the configuration, and rely on each
transfer's direction to prepare the transfers. This will enable
future removal of direction parameter from dma_slave_config.
