Staging: most: aim-sound: constify snd_pcm_ops structures

Check for snd_pcm_ops structures that are only passed as the third
argument to the function snd_pcm_set_ops. As this argument is
constant, so snd_pcm_ops structures having this property can also be
made constant.
Done using coccinelle:

@r1 disable optional_qualifier @
identifier i;

static struct snd_pcm_ops i@p = {...};
