[ALSA] hda-codec - Fix default pin config of Abit AW9D-MAX 

Fix the default pin configuration of Abit AW9D-MAX.  The board has a
broken BIOS that doesn't set the correct pin default configs, which
screws up the auto-configuration of snd-hda-intel driver.
The patch enables the override of default pin config values.
