ASoC: soc-pcm: fix hwparams min/max init for dpcm
When runtime is initialized with dpcm_init_runtime_hw(), some of the
min/max calculations assume that defaults are set. For example
calculation of channel min/max values may be done using zero-initialized
data and soc_pcm_hw_update_chan() will always return max-channels of 0
in this case. This will result in failure to open the PCM at all.
Fix the issue by calling soc_pcm_hw_init() before calling any
soc_pcm_hw_update_*() functions.
Remove the conditional code on runtime->hw.formats as this field
is anyways set in soc_pcm_hw_init().
