[Qemu-ppc] [PATCH v7 2/6] spapr_pci: encode class code including Prog IF register |

Current code missed the Prog IF register. All Class Code, Subclass,
and Prog IF registers are needed to identify the accurate device type.
For example: USB controllers use the PROG IF for denoting: USB
FullSpeed, HighSpeed or SuperSpeed.
