ASoC: Constify of_phandle_args in snd_soc_dai_link_component

ASoC core code does not modify contents of 'of_phandle_args' in 'struct
snd_soc_dai_link_component', so the pointer can be made as a pointer to
const.  This makes code safer, serves as clear annotation of core's
intentions and allows putting pointed structures in rodata (if ever
applicable).
