        src/sys/dev/pci/hdaudio: hdaudio_afg.c

Log Message:
Implement and enable headphone sensing. Slightly different from the FreeBSD
implementation in that this code does not care if the headphones are seq=15.
Instead, for each association, find any HP pins with jack sense capabilities
and if at least one has the Presense Detect bit set, enable output on all
PWCs of type HP_OUT and disable output on all PWCs of type LINE_OUT, SPEAKER,
or AUX. Do the reverse if no HP pins have the Presense Detect bit set.
