ppc/pnv: move phbbar to PnvPHB4
This MemoryRegion is simple enough to be moved in a single step. A 'stack->phb' pointer had to be introduced in pnv_pec_stk_update_map() because this function isn't ready to be fully converted to use a PnvPHB4 pointer instead. This will be dealt with in the following patches.
