I haven't checked the datasheet but the header files that defines this
macro only. And it didn't appear to be PXA3x specific.

Anyway, if this is unavailable on your hardware, the proper way would be
to place an external resistor on the board (given that you can modify
the schematics).

I'm still not convinced that driving the pad as output GPIO and then
applying a different level externally to generate an IRQ is intended.
