ALSA: intel8x0: More constifications
Apply const prefix to more places: the static tables for PCM definitions, the register tables, etc. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-9-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
