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.
