ALSA: vx: More constifications
Apply const prefix to every possible place: the static tables for DSP commands, the string tables, and register/offset tables. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-8-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
