hw/arm: Convert TYPE_ARM_SMMU to 3-phase reset
Convert the TYPE_ARM_SMMU device to 3-phase reset. The legacy method
doesn't do anything that's invalid in the hold phase, so the
conversion is simple and not a behaviour change.
Note that we must convert this base class before we can convert the
TYPE_ARM_SMMUV3 subclass -- transitional support in Resettable
handles "chain to parent class reset" when the base class is 3-phase
and the subclass is still using legacy reset, but not the other way
around.
