Input: i8042 - bypass AUX IRQ delivery test on laptops
It seems that many laptops do not fully implement AUX LOOP command in
their keyboard controllers, causing issues with touchpad detection.
We know however that almost every laptop/portable uses a PS/2 pointing
device and, even if user disables it in favor of an external mouse,
the system will not use IRQ 12 for anything else. Therefore we may
bypass AUX IRQ delivery test when running on a laptop and assume that
it is routed properly.
Just to be safe we require the box to have good PNP data in order to
bypass the test.
