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 Change-Id: I77f727f749fdd5281ff595a9237fe1e634daba96 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/17176 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
