ALSA: hda/conexant - Don't set HP pin-control bit unconditionally

commit ca3649de026ff95c6f2847e8d096cf2f411c02b3 upstream.

Some output pins on Conexant chips have no HP control bit, but the
auto-parser initializes these pins unconditionally with PIN_HP.

Check the pin-capability and avoid the HP bit if not supported.
