soc/intel/common/gpio: Add macro for interrupt GPI with driver mode

Browse source 
Adds PAD_CFG_GPI_APIC_DRIVER macros to configure interrupt pad with
driver mode. This is needed when a PAD is configured as an interrupt
such that the corresponding GPI_IS status bit can be updated by the
host controller hardware.

BUG=none
TEST=Check a GPIO pad that is used as interrupt via GpioInt in the ACPI
device _CRS method and check the interrupt has been assigned in
/proc/interrupts.
