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