Split be_hw_params_fixup function for different codecs as current common
function, leads to crash while trying to get snd_soc_dpcm with
container_of() macro in kabylake_ssp_fixup().
The crash call path looks as below:
soc_pcm_hw_params()
snd_soc_dai_hw_params(codec_dai, substream, &codec_params);
rtd->dai_link->be_hw_params_fixup(rtd, params)
kabylake_ssp_fixup()
In this case, codec_params is just a copy of an internal structure and is
not embedded into struct snd_soc_dpcm thus we cannot use
container_of() on it.
v1 -> v2:
- Extract dmic from SSP0 as every BE should have own fixup function.
v2 -> v3:
- Restore naming in the dapm route table to not confuse with other
drivers
- Fixed indentations
