My qom-cpu-10 series may help here, it turns cpu_dump_state() into a
simple helper function calling CPUClass::dump_state(). So a Cortex-A5x
class_init or TARGET_AARCH64 for the base class_init would simply assign
the 64-bit version of the callback, leaving 32-bit target unaffected
(note: I didn't read the whole patch).
