soc/intel/common/block/gpio: Allow GPI to be dual-routed
This change adds new macros to GPIO common library helpers to allow a GPI pad to be dual routed using PAD_CFG_GPI_DUAL_ROUTE. It also adds a helper macro to configure a pad for IRQ and wake. Above macros are guarded using a newly added Kconfig option SOC_INTEL_COMMON_BLOCK_GPIO_DUAL_ROUTE_SUPPORT that is selected only by SoCs that have been validated to allow dual route of GPIs. Currently, this config is selected only for APL/GLK/SKL/KBL that have been validated to work with dual-routing of GPIs for IRQ and wake.
