target/ppc: Introduce 'PowerPCCPUClass::spapr_logical_pvr'
Introduce 'PnvChipClass::spapr_logical_pvr' to know corresponding logical PVR of a PowerPC CPU. This helps to have a one-to-one mapping between PVR and logical PVR for a CPU, and used in a later commit to handle cases where PCR of two generations of Power chip is same, which causes regressions with compat-mode.
