iommu/exynos: Fix driver initialization sequence

Browse source

Registering a SYSMMU platform driver might directly trigger initializing
IOMMU domains and performing the initial mappings. Also the IOMMU core
might use the IOMMU hardware once it has been registered with
iommu_device_register() function. Ensure that all driver resources are
allocated and initialized before the driver advertise its presence to the
platform bus and the IOMMU subsystem.
