iommu/mediatek: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/iommu/Kconfig:config MTK_IOMMU_V1 drivers/iommu/Kconfig: bool "MTK IOMMU Version 1 (M4U gen1) Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not even used by this driver, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.
