target/ppc: Remove PowerPC 601 CPUs

Browse source 
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.
