RFC iommu/arm-smmu: Add support for adding masters/clocks using generic bindings

This series adds support for xlate callback to add master devices configs using generic bindings and clocks/regulators required to access smmu.

OF_IOMMU_DECLARE is used to register and probe the smmu controller devices before the masters are added in of_platform_populate. Here, we are registering only the smmu driver and iommu_ops. The smmu device registration is not done in OF_IOMMU_DECLARE to avoid early smmu probe, because the clocks if any required for the controller are not yet ready.

So the idea here is to get the right direction in adding this support.
