iommu/exynos: Init from dt-specific callback instead of initcall
iommu/exynos: Init from dt-specific callback instead of initcall

This patch introduces IOMMU_OF_DECLARE-based initialization to the
driver, which replaces subsys_initcall-based procedure.
exynos_iommu_of_setup ensures that each sysmmu controller is probed
before its master device.
