iommu/arm-smmu-v3: Make the kunit into a module
It turns out kconfig has problems ensuring the SMMU module and the KUNIT
module are consistently y/m to allow linking. It will permit KUNIT to be a
module while SMMU is built in.
Also, Fedora apparently enables kunit on production kernels.
So, put the entire kunit in its own module using the
VISIBLE_IF_KUNIT/EXPORT_SYMBOL_IF_KUNIT machinery. This keeps it out of
vmlinus on Fedora and makes the kconfig work in the normal way. There is
no cost if kunit is disabled.
