[PATCH 09/18] dma: edma: Simplify direction configuration in edma_config_pset()

[Peter Ujfalusi]

We only support DEV_TO_MEM or MEM_TO_DEV directions with edma driver and the
check for the direction has been already done in the function calling
edma_config_pset().
The error reporting is redundant and also the "else if ()" can be removed.
