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 just becomes device_initcall for non-modules, the
init ordering remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
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.
