ALSA: hda - Add pin-sense trigger when needed for Realtek codecs 

Realtek codecs require the pin-sense trigger call before actually
reading the pin-sense.  Without this, the pin-detection might not be
done accurately.

This patch adds the pin-capability check and issues the trigger call
if required.
