target-xtensa: Mark as unmigratable

Browse Source 
There was no CPU_SAVE_VERSION defined, so neither "cpu_common" VMState
nor cpu_{save,load}() were registered. Their implementation was no-op.
Therefore there is no backwards compatibility to keep, so mark XtensaCPU
as unmigratable at device level.
