ACPI: x86: Extend Lenovo Yoga Tab 3 quirk with skip GPIO event-handlers
Depending on the secureboot signature on EFI\BOOT\BOOTX86.EFI the
Lenovo Yoga Tab 3 UEFI will switch its OSID ACPI variable between
1 (Windows) and 4 (Android(GMIN)).
In Windows mode a GPIO event handler gets installed for GPO1 pin 5,
causing Linux' x86-android-tables code which deals with the general
brokenness of this device's ACPI tables to fail to probe with:
[ 17.853705] x86_android_tablets: error -16 getting GPIO INT33FF:01 5
[ 17.859623] x86_android_tablets x86_android_tablets: probe with driver
which renders sound, the touchscreen, charging-management,
battery-monitoring and more non functional.
Add ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS to the existing quirks for this
device to fix this.
