ALSA: ice1712: add const to snd_ak4xxx_private structures

Declare snd_ak4xxx_private structures  as const as they are only passed
to the function snd_ice1712_akm4xxx_init. This argument is of type const,
so make the structures const.
Done using Coccinelle:

@match disable optional_qualifier@
identifier s;
position p;
@@
static struct snd_ak4xxx_private s@p={...};

@good1@
identifier match.s;
position p;
@@
snd_ice1712_akm4xxx_init(...,&s@p,...)

@bad@
identifier match.s;
position p!={match.p,good1.p};
@@

@depends on !bad disable optional_qualifier@
identifier match.s;
@@
static
+const
struct snd_ak4xxx_private s={...};
