target-ppc: Add pvr_match() callback
So far it was enough to have a base PVR value and mask per CPU family such as POWER7 or POWER8. However there CPUs which are completely architecturally compatible but have different PVRs such as POWER7/POWER7+ and POWER8/POWER8E. For these CPUs, top 16 bits are CPU family and low 16 bits are the version. The families have PVR base values different enough so defining a mask which would cover both (or potentially more) CPUs within the family is not possible. This adds a pvr_match() callback to PowerPCCPUClass. The default handler simply compares PVR defined in the class. This implements ppc_pvr_match_power7/ppc_pvr_match_power8 callbacks for POWER7/8 families. These check for POWER7/POWER7+ and POWER8/POWER8E. This changes ppc_cpu_compare_class_pvr_mask() not to check masks but use the pvr_match() callback. Since all server CPUs use the same mask, this defines one mask value - CPU_POWERPC_POWER_SERVER_MASK - which is used everywhere now. This removes other mask definitions. This removes pvr_mask from PowerPCCPUClass as it is not used anymore. This removes pvr initialization for POWER7/8 families as it is not used to find the class, the pvr_match() callback is used instead.
