iommu/tegra-smmu: Pass correct fwnode to iommu_fwspec_init()

Browse Source 
iommu_fwspec_init() expects to receive the fwnode corresponding to the
IOMMU device, not the fwnode corresponding to the client device being
probed.

Fix arm_smmu_configure() to pass the correct fwnode to
iommu_fwspec_init().
