ASoC: Constify passed data to core function

ASoC: Constify passed data to core function

Several ASoC functions receive pointers to data which is not modified,
e.g. pointers to 'snd_soc_dai', 'snd_soc_pcm_runtime',
'snd_pcm_hw_params' and 'snd_soc_dai_link'.

All these pointers can be made as a pointer to const.  This makes code
safer, serves as clear annotation of function's intentions (no ownership
passed to the function, no modifications) and allows putting pointed
structures in rodata (if ever applicable).
