This feels like something we should be fixing at the core level - as far
as I can tell there's no PXA specific duplication going on here, it's
the core that's triggering the suspend operation twice so it's likely
that there's going to be problems on other platforms somehow.  Or is
there something PXA specific I'm missing here?
