MLK-16224-2: ASoC: dmaengine_pcm: add fifo_num to snd_dmaengine_dai_dma_data 

In order to support multi-fifo sdma script, the audio driver need to send
the fifo number to dma driver through dma_slave_config, and the cpu_dai
driver should config fifo_num for the audio platform driver, then platform
driver can config fifo_num to dma.
So add new variable fifo_num for struct snd_dmaengine_dai_dma_data.
