It appears that after commit to the gpio-dwapb driver the quirk for Intel
Galileo Gen 2 stopped working. I tried a few approaches but none of them
worked besides the fact that they copy like a ~10% of the gpiolib-acpi
functionality.

Instead I decided to come back to a mix of v1 [1] of the initial series
(the v3 has been applied) and Mika's suggestion about using gpio_to_desc()
API.

Unfortunately it requires to have a quirk in the core, but in comparison
to v1 it much less intrusive and doesn't use any predefined numbers.

I would like to create an immutable branch and send TWIMC (GPIO and ACPI
subsystems I guess). This is material for v5.12-rcX.
