ALSA: hda - Fix mute-LED GPIO pin for HP dv series

Old HP dv series seem to use the GPIO pin 0 for controlling the mute LED
although the pin is a large package, where the newer models use GPIO 3
in such a case.  For fixing the regression from the previous kernels,
set spec->gpio_led statically for these model quirks.
