[ALSA] Add a new quirk for mute-LED and HP-only.

Browse Source 
Modules: AC97 Codec,ATIIXP driver,Intel8x0 driver

This patch adds a new quirk for ac97 hardware that combines the existing
AC97_TUNE_MUTE_LED and AC97_TUNE_HP_ONLY quirks.  This is needed for several
current HP laptops.  Additionally, it adds the HP nx6125 to the
AC97_TUNE_MUTE_LED list.

Fixed for the latest version of ALSA by Takashi Iwai <tiwai@suse.de>.
