Thanks.  I prefer keeping the old COEF as a generic one, so let's move
ALC668_FIXUP_ASUS_G751 with the pin-config fix and chain to a new one
ALC668_FIXUP_MIC_COEF.

The fix patch is below.

Subject: [PATCH] ALSA: hda - Fix headphone pin config for ASUS G751

BIOS on ASUS G751 doesn't seem to map the headphone pin (NID 0x16)
correctly.  Add a quirk to address it, as well as chaining to the
previous fix for the microphone.
