Bug description:
  [Impact]
  IRQ storm generated from touchpad after S3, renders touchpad useless.

  [Fix]
  gpiolib routines expect pin offset instead of pin number. Passing correct
  pin offset can solve the issue.

  [Test]
  With the patch applied the issue doesn't happen anymore on HP Zbook 17 
  G5.

  [Regression Potential]
  Low. Though there are many users of pinctrl-intel, this make it 
  correctly uses gpiolib.
