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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
