Blackfin: dpmc: do not save/restore EVT0/EVT1/EVT4 when hibernating
EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int disable" region. None of these are used by software (or even hardware), so don't bother saving/restoring them when we hibernate since nothing ever uses these in Linux (the only thing they would be useful for is core-memory scratch, but that's just crazy talk).
