The existing code stores the amount of memory allocated for a TCE table.
At the moment it uses @offset which is a virtual offset in the TCE table
which is only correct for a one level tables and it does not include
memory allocated for intermediate levels. When multilevel TCE table is
requested, WARN_ON in tce_iommu_create_table() prints a warning.

This adds an additional counter to pnv_pci_ioda2_table_do_alloc_pages()
to count actually allocated memory.

I was sure I sent it already but could not find it anywhere so reposting.
Sorry if it is a duplicate.

Stable?

No, this is for DDW patchset I recently posted and which did not get to any 
release yet.
