UPSTREAM: acpi_device: Add macro for GpioInt that uses both polarity

Browse source 
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
