[ALSA] cmipci - Disable integrated mpu401 as default
Enable the support of mpu401 PCI port only when mpu_port=1 module option is given, i.e. disabled as default. It turned out that the check of integrated midi port isn't perfect and caused hang-ups on some boards. Signed-off-by: Takashi Iwai <tiwai@suse.de>
