ALSA: hda - Fix docking output for IDT 92HD8xx codecs 

This patch fixes docking output support for IDT 92HD81/83/88 family codecs.
Typically one of ports 0xE or 0xF is used for docking output, while only
port 0xF is common on all the three codec families.  We don't want the
pin to select the analog mixer here.
