Commit 262af557dd75(powerpc/powernv: Enable M64 aperatus for PHB3)
introduces the concept of compound PE, and they are linked together to
master PE's slaves lish_head with the list field. While this field is
usually used to linked to the phb->ioda.pe_list to represents the PE is
used.
This patch introduces a field "compound" to link those compound PEs.
