    xen: arm: Assume level triggered means high, not low.
    
    When reading back the ICFG register we cannot know the polarity of the
    configuration, just that it is level or edge.
    
    Since falling edge and low level are invalid for SPIs we should assume
    rising edge and high level (we have no better information for PPIs, so
    it'll have to do).
    
    We already assumed rising edge, switch to high level as well.
