ALSA: bebob: Add a quirk of data blocks for MIDI messages for some M-Audio devices
The firmwares for M-Audio Firewire 410/1814 and ProjectMix I/O has a quirk to ignore MIDI messages in data blocks more than 8. This commit uses a flag which Fireworks uses for a similar quirk. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
