ASoC: rt5514: constify snd_soc_dai_ops structure

This structure is only stored in the ops field of a snd_soc_dai_driver
structure. That field is declared const, so snd_soc_dai_ops structures
that have this property can be declared as const also.

Also, make rt5514_aif_dai_ops static, as it is not used outside this
module.
