ALSA: fireface: constify ALSA specific operations
ALSA fireface driver has ALSA specific operations for MIDI/PCM data. Structured data for the operations can be constified. Additionally, The structured data can be function local. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
