cpu_{save,load} were no-ops, so de facto it is unmigratable and no
backwards compatibility to keep. Therefore mark the MicroBlazeCPU as
unmigratable at device level the QOM way and suppress "cpu_common"
VMState registration by dropping CPU_SAVE_VERSION.

Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.

Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.

Move common parts of mips cpu_state_reset() to mips_cpu_reset().
