ASoC: Intel: catpt: Drop manipulation of the obsolete direction flag

Setting up direction for struct dma_slave_config is obsolete, see the
description of the struct.  The transfer performed by the catpt-driver
is also always DMA_MEM_TO_MEM not DMA_MEM_TO_DEV with preparation step
being dmaengine_prep_dma_memcpy().

DW's ->device_prep_dma_memcpy() always fixes the direction to
DMA_MEM_TO_MEM even if its user fails to do so, see
drivers/dma/dw/core.c.   While the change impacts number of checks done
by ->device_config() - p/m buswidth checks are skipped - fields being
fixed up in those i.e.: .dst_addr_width and .src_addr_width, do not take
part in DMA_MEM_TO_MEM transfer.
