b614583721 ASoC: zte: spdif: remove duplicate initialization of dma_data
dma_data is being initialized twice, remove the unused first
initialization and use the latter one instead.  Fixed clang warning:

"warning: Value stored to 'dma_data' during its initialization is
never read"

a205c159f9 ASoC: zx-i2s: flip I2S master/slave mode
The SND_SOC_DAIFMT_MASTER bits are defined to specify the master/slave
mode for Codec, not I2S.  So the I2S master/slave mode should be flipped
according to SND_SOC_DAIFMT_MASTER bits.

6a9a440681 ASoC: zx-i2s: fix harsh noise with 16-bit audio
The audio parameter setup in zx_i2s_hw_params() works fine with 32-bit
samples, but for 16-bit ones, all we can hear is harsh noises.
As suggested by vendor driver code, DMA burst size and TS width should
always be 32 bits, no matter audio sample is 16-bit or 32-bit.

Follow the suggestion above to fix the harsh noise issue seen with
16-bit audio samples.

66ead502af ASoC: zx-i2s: introduce pclk for zx2967 family
The pclk is necessary for zx2967 I2S controller. the driver
currently doesn't handle it. This is something we need to fix.

In turn, the driver supports zx296718's I2S controller.

By the way, this patch also change the clock name from tx to wclk
to make it clear.

de7975c2a4 ASoC: zte: spdif and i2s drivers are not zx296702 specific
ZTE ZX SPDIF and I2S drivers can work on not only ZX296702 but also
other ZTE ZX family SoCs like ZX296718, which is an arm64 platform.
Let's make a few renaming and tweak the Kconfig a bit to get the drivers
available for other ZTE ZX platforms.

Use devm_* API to fix leaks in current code.
1. Use devm_kzalloc to fix memory leak for zx_i2s when unload the module.
2. Use devm_snd_soc_register_component to ensure component is unregistered
   when unload the module.
