ppc/pnv: move phbbar to PnvPHB4

Browse source 
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.
