IRQ storm generated from touchpad after S3, renders touchpad useless.

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

With the patch applied the issue doesn't happen anymore on HP Zbook 17

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

  pinctrl: intel: remap the pin number to gpio offset for irq enabled
