skylake: Add GPIO macro for configuring 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
