gpiolib: acpi: Add a quirk for Acer Nitro V15

It is reported that on Acer Nitro V15 suspend only works properly if the
keyboard backlight is turned off. In looking through the issue Acer Nitro
V15 has a GPIO (svenkatr#8) specified in _AEI but it has no matching notify device
in _EVT. The values for GPIO svenkatr#8 change as keyboard backlight is turned on
and off.

This makes it seem that GPIO svenkatr#8 is actually supposed to be solely for
keyboard backlight.  Turning off the interrupt for this GPIO fixes the issue.
Add a quirk that does just that.
