ALSA: declare snd_kcontrol_new structures as const
Declare snd_kcontrol_new structures as const as they are only passed an
argument to the function snd_ctl_new1. This argument is of type const,
so snd_kcontrol_new structures having this property can be made const.
Done using Coccinelle:

static struct snd_kcontrol_new x@p={...};
