Function nand_setup_cmd_params has 2 goals- -Initialize the cmd_params field so that it can be used to send and read commands from the device. -Get a bus address for the allocated memory to transfer to the device. Replace the combination of devm_kzalloc and _pa() with dmam_alloc_coherent. Coherent mapping guarantees that the device and CPU are in sync.

Audio ----- - Move to using the ALSA framework not faking it - Fix the wrong user page DMA (moving to ALSA may fix that too) NAND ---- - Remove excess checking of parameters in calls - Use dma coherent memory not kmalloc/__pa for the memory (this is just a cleanliness issue not a correctness one)
