iommu/qcom: 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 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.
