Subject: drm/i915/icl: fix gmbus gpio pin mapping
Git-commit: af1f1b81130e82a1ee62fe48aa09e6bdab6e68f4
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
ICP has GPIO pin 1/2 mapped to combo-phy ports & GPIO pins 9/10/11/12
mapped to tc ports[1-4].
This patch defines GPIOCTL registers for GPIO pins 9-12 & uses them in GPIO
pin mapping table.
