powerpc/mpc83xx: Add the missing set_freezable() for agent_thread_fn()
The kernel thread function agent_thread_fn() invokes the try_to_freeze()
in its loop. But all the kernel threads are non-freezable by default.
So if we want to make a kernel thread to be freezable, we have to invoke
set_freezable() explicitly.
