[PATCH 1/6] ASoC: Constify of_phandle_args in snd_soc_dai_driver

[Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>]

ASoC core code does not modify contents of 'of_phandle_args' in 'struct
snd_soc_dai_driver', 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).
