v2: Omit these two commits:
  pinctrl: intel: Do pin translation when lock IRQ
  Revert "pinctrl: intel: Do pin translation when lock IRQ"

[Impact]
Intel pinctrl doesn't work.
There's a WWAN card needs to use pinctrl to reset itself after firmware
update. Currently we can't use pinctrl to reset it.

[Fix]
Translate GPIO to pinctrl pins correctly.

[Test]
The WWAN reset function works once the fix is applied.

[Regression Potential]
Low. Limits to pinctrl-intel and it's in mainline for a while.

Javier Arteaga (1):
  pinctrl: intel: Implement intel_gpio_get_direction callback

Mika Westerberg (1):
  pinctrl: intel: Do pin translation in other GPIO operations as well
