acpi_device: Add macro for GpioInt that uses both polarity
GPIO edge interrupts can report that they are ActiveBoth and will generate an interrupt event on both rising and falling edges. Add a macro so this type of GPIO interrupt can be used. BUG=b:35581264 BRANCH=none TEST=successfully use this interrupt type on Eve Change-Id: I91408386538e442bddcacc9840e0aa14370a446c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18834 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
