[PATCH] hw/m68k/mcf52xx: Replace hw_error() by qemu_log_mask()

[Philippe Mathieu-Daudé]

hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.

When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
