target/ppc: Move PowerPCCPUClass definition to 'cpu.h'

The OBJECT_DECLARE_CPU_TYPE() macro forward-declares the
PowerPCCPUClass type. This forward declaration is sufficient
for code in hw/ to use the QOM definitions. No need to expose
the structure definition. Keep it local to target/ppc/ by
moving it to target/ppc/cpu.h.
