Public bug reported:

[Impact]
Cirrus Logic AMP still doesn't work on Zbook Studio G9. Moreoever, The
audio mute LEDs stop working after the said SRU.

[Fix]
Correcly interpret the debounce time from ACPI to gpiolib, and apply the
correct quirk for the audio mute LEDs.

[Where problems could occur]
It's possible that some hardwares rely on the "wrong" debounce time to
work, however the fix is to increase the debounce time, so it's more
forgiving than decreasing.

The LED fix is only applied to one system, so it's specifi and won't
cause too much trouble.
