[Fix] Apply ALC285_FIXUP_HP_GPIO_AMP_INIT quirk to expose GPIOs for controlling LEDs and initialing AMP. [Test] Built a test kernel with applying this patch, the mute/micmute LEDs are work as expected. The internal speaker could play the sounds from left and right channels. [Where problems could occur] This quirk is specific for these two platforms. It should not cause the regression to other systems.
