powerpc/powernv/ioda: Clean up IOMMU group registration

Browse source

The existing code has 3 calls to iommu_register_group() and
all 3 branches actually cover all possible cases.

This replaces 3 calls with one and moves the registration earlier;
the latter will make more sense when we add TCE table sharing.
