There is no actual bleeding procedure for power steering fluid.
If there's air in the system, and you've fixed any leaks that might be there, then all you need to do is top up the reservoir, start the engine, and crank the steering wheel from side to side a few times....or just drive it.
The natural act of driving it, (as long as the pump is cranking/turning and doing it's thing), will cause the air to rise to the top and dissipate.
