soc/intel/skylake: Add GPIO macros for IOxAPIC and SCI

Add two GPIO macros:
  1. PAD_CFG_GPI_APIC_EDGE allows a pin to be route to the
     APIC with input assuming the events are edge triggered.

  2. PAD_CFG_GPI_ACPI_SCI_LEVEL to route the general purpose
     input to SCI assuming the events are level triggered.
