Input: goodix - accept ACPI resources with gpio_count == 3 && gpio_int_idx == 0
Some devices list 3 Gpio resources in the ACPI resource list for
the touchscreen:
1. GpioInt resource pointing to the GPIO used for the interrupt
2. GpioIo resource pointing to the reset GPIO
3. GpioIo resource pointing to the GPIO used for the interrupt
Note how the third extra GpioIo resource really is a duplicate
of the GpioInt provided info.
Ignore this extra GPIO, treating this setup the same as gpio_count == 2 &&
gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook
Colossus W803 rugged tablet and likely also on the CyberBook_T116K.
