ASoC: fsi: use SNDRV_DMA_TYPE_DEV for sound buffer
Current fsi driver is using SNDRV_DMA_TYPE_CONTINUOUS for snd_pcm_lib_preallocate_pages_for_all(). But, it came from original dma-sh7760.c, and no longer needed. This patch exchange its parameter, and removed original dma mapping and un-needed dma_sync_single_xxx() from driver.
