skylake: Add GPIO macro for configuring inverted APIC input

Hardware / Coreboot - Duncan Laurie [chromium.org] - 28 October 2016 11:59 UTC

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
