ALSA: hda - Add hp-dv4 model for IDT 92HD71bx

It turned out that HP dv series have inconsistent the mute-LED GPIO
mapping among various models.  dv4/7 seem to use GPIO 0 while dv 5/6
seem to use GPIO 3.  The previous commit
  26ebe0a2
  ALSA: hda - Fix mute-LED GPIO pin for HP dv series
breaks dv5/6.

This patch adds the new quirk model, hp-dv4, to handle HP dv4/7
separately from HP dv5/6.
