MT8192 determines the I2S clock rates according to the sampling rates.
There is only 1 set of I2S in between MT8192 and RT5682. If playing and
capturing via RT5682 in different sampling rates, the I2S data will be
corrupted.
Adds format constraints to the corresponding DAI links to make sure the
sampling rates are symmetric.

If the DTS property is specified, the DP bridge should populate a
"hdmi-codec" platform device (sound/soc/codecs/hdmi-codec.c).
The "hdmi-codec" device is the communication relayer between the ASoC
machine driver and the DP bridge. For example:
- Notifies DP bridge when setting hw_param.
- Notifies ASoC when jack detection events.

Returns snd_soc_component_set_jack() directly in mt8192_rt5682_init.
No need to have another block to check the return value.

bclk_ratio is unused. Removes bclk_ratio and .set_bclk_ratio callback.
Removes snd_soc_dai_set_bclk_ratio() in a few machine drivers which are
obviously using rt1015.

Renames common symbols from "mt8192_mt6359_rt1015_rt5682" to
"mt8192_mt6359".
They will share between a few machine drivers on MT8192 and MT6359
with some different audio components.

We can choose to drop away any length of data from the beginning according
to project needs. Some projects don't want to throw away any data, because
they want to use recorded data to do echo cancellation, so they have to
make sure that they are aligned with the reference data as much as
possible. Or there are other algorithms in the upper layer to eliminate
this noise. Or some projects want to eliminate this noise form the kernel
layer. However, the minimum recommended value is 50ms to skip pop noise.
