iommu/io-pgtable-arm: Call ->tlb_flush_walk() and ->tlb_flush_leaf()

Browse source 
Now that all IOMMU drivers using the io-pgtable API implement the
->tlb_flush_walk() and ->tlb_flush_leaf() callbacks, we can use them in
the io-pgtable code instead of ->tlb_add_flush() immediately followed by
->tlb_sync().
