[ALSA] hda-codec - Support multiple headphone pins

Some machines have multiple headpohne pins (usually on the lpatop
and on the docking station) while the current hda-codec driver
assumes a single headphone pin.  Now it supports multiple hp pins
(at least for detection).
The sigmatel 92xx code supports this new multiple hp pins.
It detects all hp pins for auto-muting, too.
Also, the driver checks speaker pins in addition.  In some cases,
all line-out, speaker and hp-pins coexist.
