Sjoerd Simons d5fec4ca7a Alsa: Correct port availability with multiple jacks 
In case there are two independent jacks for one port (e.g. Dock
Headphone Jack and Headphone Jack), the availability ends up being
incorrect if the first one was _NO (not plugged) and the second gets
_YES (plugged). Also pulse complains about the state being inconsistent
which isn't true.

Fix this by preferring more precise states (yes/no) over unknown and yes
over others. However in case a plugged jack makes the port unavailable
let that overrule everything else.
