dma: Support for 3 bytes word size
Add DMA_SLAVE_BUSWIDTH_3_BYTES to dma_slave_buswidth for engines and users to select 3 bytes as bus width. For example eDMA can be configured to use 3bytes mode and in audio we have formats stored on 3bytes in memory (_XXX_3LE) where this new bus width can be used.
