ALSA: ac97: Constify snd_ac97_bus_ops definitions

Now snd_ac97_bus() takes the const ops pointer, so we can define the snd_ac97_bus_ops locally as const as well for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Takashi Iwai <[email protected]>
