[PATCH 1/9] iommu/arm-smmu: Switch to arch_initcall for driver registration

[Andreas Herrmann]

This should ensure that arm-smmu is initialized before other drivers
start handling devices that propably need smmu support.

Also remove module_exit function as we most likely never want to
unload this driver.
