This reverts commit e436576b02.
That commit is very broken, and seems to have missed the fact that
CONFIG_ARM_SMMU_V3 is not just a yes-or-no thing, but also can be
modular.
So it caused build errors on arm64 allmodconfig setups:
ERROR: modpost: "arm_smmu_make_cdtable_ste" [drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3-test.ko] undefined!
ERROR: modpost: "arm_smmu_make_s2_domain_ste" [drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3-test.ko] undefined!
ERROR: modpost: "arm_smmu_make_s1_cd" [drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3-test.ko] undefined!
...
(and six more symbols just the same).

Nothing in there is active if CONFIG_ARM_SMMU_V3 is not enabled, so the whole
directory can depend on that switch as well.

The Arm SMMU drivers are getting fat on vendor value-add, so move them
to their own subdirectory out of the way of the other IOMMU drivers.
