Add support for SMMU drivers built as modules to the ACPI/IORT device probing path, by deferring the probe of the master if the SMMU driver is known to exist but has not been loaded yet. Given that the IORT code registers a platform device for each SMMU that it discovers, we can easily trigger the udev based autoloading of the SMMU drivers by making the platform device identifier part of the module alias.
