soc/intel/common/block/gpio: Allow GPI to be dual-routed

Browse Source 
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.
