[PATCH/RFC 3/4] ARM: shmobile: extend MMCIF DMA client configuration entries

To prepare for MMCIF driver transition to the dma_request_slave_channel()
API the MMCIF DMA client configuration entries in the slave configuration
table have to be extended with device ID and DMA transfer direction fields.

This is just an example. Eventually all DMA client configurations on all 
affected platforms should be converted.
