ALSA: pcm: More constifications
Apply const prefix to more possible places: the string tables for PCM format and co, the table for the PCM type helpers, etc. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-6-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
