Sorry it took a while to actually start implementing the quirk for your case.
Here I'm asking for the following things:

1) what is the marketing name of the device you have problems with?
(I believe it's available on the free market, correct?);

2) does it have any BIOS updates and, if it has, does it fix the issue?

3) can you apply patches 2,3,4,5 from this series (the first one is buggy and
not needed for you) and replace the hack I mentioned earlier with

	ret = intel_gpio_set_high_impedance(pctrl, 3);
	if (ret)
		return ret;

somewhere at the end of intel_pinctrl_probe()?

Does it still work as expected?
