iommu/mediatek: Allow building as module

Browse Source 
The IOMMU in many SoC depends on the MM clocks and power-domain which
are device_initcall normally, thus the subsys_init here is not helpful.
This patch switches it to module_platform_driver which also allow the
driver built as module.

Correspondingly switch the config to tristate, and update the
iommu_ops's owner.
