target/ppc: Remove PowerPC 601 CPUs
The PowerPC 601 processor is the first generation of processors to implement the PowerPC architecture. It was designed as a bridge processor and also could execute most of the instructions of the previous POWER architecture. It was found on the first Macs and IBM RS/6000 workstations. There is not much interest in keeping the CPU model of this POWER-PowerPC bridge processor. We have the 603 and 604 CPU models of the 60x family which implement the complete PowerPC instruction set.
