ASoC: davinci-pcm: expand the .formats

Based on the data_type test in ping_pong_dma_setup, davinci-pcm is capable of
handling data of width up to and including 32bits.

"
	if ((data_type == 0) || (data_type > 4)) {
		printk(KERN_ERR "%s: data_type=%i\n", __func__, data_type);
		return -EINVAL;
	}
"

Update the .format member of the snd_pcm_hardware instances it registers to
reflect this capability.
