skylake: Add GPIO macro for confuring inverted APIC input

Add a GPIO macro that allows a pin to be routed to the APIC with
    the input inverted.  This allows a normal interrupt to get used as
    a GPE during firmware and still be used as a perhiperal interrupt
    in the kernel.

BUG=chrome-os-partner:58666
    TEST=boot en eve and use TPM IRQ in firmware and OS
