Intel Baytrail support has been in mainline kernel for quite some time
already. The driver is drivers/pintctrl/intel/pinctrl-baytrail.c.

Also the ICH GPIO block is not compatible to Baytrail which is why there
is a separate driver in the first place. Have you tested this series on
Baytrail?

All Baytrails I've seen expose the GPIO device via ACPI namespace so
there should be no need for the above two patches.
