iommu/arm-smmu: Convert struct device of_node to fwnode usage

Current ARM SMMU driver rely on the struct device.of_node pointer for
device look-up and iommu_ops retrieval.

In preparation for ACPI probing enablement, convert the driver to use
the struct device.fwnode member for device and iommu_ops look-up so that
the driver infrastructure can be used also on systems that do not
associate an of_node pointer to a struct device (eg ACPI), making the
device look-up and iommu_ops retrieval firmware agnostic.
