On the Lenovo IdeaPad Slim 3 15ABR8 (82XM), the touchscreen
(GTCH7503:00) GPIO interrupt on pin 10 is armed as a wake source. As
soon as the system enters s2idle suspend the interrupt fires, causing
an immediate spurious resume, so suspend is unusable.

Disabling wakeup for the device via sysfs or booting with
gpiolib_acpi.ignore_wake=GTCH7503:00@10 avoids the problem, so add
a DMI quirk that ignores wakeup on that pin.
