Allow cold-plug of smmuv3 device to virt if there is no machine
wide legacy smmuv3 or a virtio-iommu is specified.
Device tree support for new smmuv3 dev is limited to the case where
it is associated with the default pcie.0 RC.

Although this change does not affect functionality at present, it is
required when we add support for user-creatable SMMUv3 devices in
future patches.

With the soon to be introduced user-creatable SMMUv3 devices for
virt, it is possible to have multiple SMMUv3 devices associated
with different PCIe root complexes.
Update IORT nodes accordingly.

default_bus_bypass_iommu tells us whether the bypass_iommu is set
for the default PCIe root bus. Make sure we check that before adding
the "iommu-map" DT property.
