iommu/rockchip: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/iommu/Kconfig:config ROCKCHIP_IOMMU
drivers/iommu/Kconfig: bool "Rockchip IOMMU Support"
...meaning that it currently is not being built as a module by anyone.
The bind/unbind/remove was already explicitly disabled in commit
98b72b94de
("iommu/rockchip: Prohibit unbind and remove").
Lets remove the remaining traces of modular infrastructure, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init was not in use by this code, 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.
