acpi_device: Add macros for GPIO interrupts
Add individual macros for the various interrupt types so they can be used in devicetree. BUG=chrome-os-partner:58666 TEST=nothing uses this yet, will be used in an upcoming commit Change-Id: I2a569f60fcc0815835615656b09670987036b848 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18392 Tested-by: build bot (Jenkins) Reviewed-by: Furquan Shaikh <furquan@google.com>
