[ALSA] cmipci - Allow to disable integrated FM port

Browse source 
The driver didn't allow to disable the integrated FM port (if available),
and this annoyed people who don't want FM port.  Now fm_port=0 disables
the FM port unconditionally.  fm_port=1 is used for enabling the integrated
FM port (as default).
Also fixed the documentation about this option.
Fix ALSA bug#2491.
