Touchpad and touchscreen don't work on TGL-H laptops.

Update GPIO mapping so the values can match between Linux and BIOS.

After applying the patch, both touchpad and touchscreen can work

[Where problems could occur]
If somehow any of the new pin value is incorrect, it can break devices
that require Intel GPIO to work.
