simple sound card family are using very similar style, but because of its
historical reason, there are small differences. For example pointer style,
function name, caller postion etc...
This patch synchronized simple card style to other simple card family.

Otherwise, we will have below error, and can't use it.

The release_firmware() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

The DMA channel names are specified through struct snd_dmaengine_pcm_config
rather than using SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag when
booting with devicetree in order to properly support deferred probing.
Without this change the sound machine driver initialization can complete
successfully with unavailable DMA resources.

Ensure they secondary DAI device is freed properly when asoc_dma_platform
registration fails. This change is needed for proper deferred probe support
and will help preventing situations when the CPU DAI's initialization
completes without required DMA resources.

The TDM mode using PCM format now has two-bit right shift due to the
format configuration in the driver. According to Figure 4-13 in the
CS53L30 datasheet, using ASP_SCLK_INV = 0 and SHIFT_LEFT = 1 should
be the correct combination to create one-bit right shift for the DSP
type A format.
