ppc/pnv: Compute the PHB index from the PHB4 PEC model
Use the num_stacks class attribute to compute the PHB index depending
on the PEC index :
* PEC0 provides 1 PHB (PHB0)
* PEC1 provides 2 PHBs (PHB1 and PHB2)
* PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5)
The routine pnv_pec_phb_offset() is a bit complex but it also prepares
ground for PHB5 which has a different layout of stacks: 3 per PECs.
