iommu/ipmmu-vmsa: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/iommu/Kconfig:config IPMMU_VMSA drivers/iommu/Kconfig: bool "Renesas VMSA-compatible IPMMU" ...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. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
