[PATCH v2 13/33] target/m68k: Register CPUClass::exception_name() handler

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

Expose m68k_exception_name() prototype and register it
as the CPUClass::exception_name() handler, so the common
exception logging can resolve M68k exception codes to names.
