This patch adds struct snd_soc_dai_ops :: set_sysclk. But, it do nothing, since rsnd sysclk is controlled by ADG. Without this patch, simple-card init will be failed if DT case.

We should fix the simple-card code so that it does not need this rather than adding empty functions to all the drivers - I'd expect it to handle -ENOTSUPP as not an error.
