[Impact]
* Mute and micmute LED are not work accurately on HP ZBook Fury 15/17 G7
Mobile Workstation when muting corresponding audio devices.
* The right channel of internal speaker has not sound.

[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.
