Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).
