ALSA: line6: constify snd_kcontrol_new structures

Declare snd_kcontrol_new strcutures as const as they are only passed as
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 too.
Done using Coccinelle:

@r disable optional_qualifier@
identifier x;
position p;

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

@ok@
identifier r.x;
position p;

@bad@
position p != {r.p,ok.p};
identifier r.x;
