CHRP needs the heartbeat function called on all cpus, IIRC.

Clearly the heartbeat_count needs to be per-cpu or else pushed into
the heartbeat function.  How about we make it just

	if (ppc_md.heartbeat)
		ppc_md.heartbeat();

and let the heartbeat function do the if (!smp_processor_id()) and the
if (!heartbeat_count--) if it wants?
