Request for Comment: Adding options related to Power Saving

[morrownr]

There are some cases when it makes sense to disable Power Saving and there have been cases reported over the years where disabling Power Saving made adapters usable. I have no problems and only had one report of someone having a problem with this driver on a modern OS but I am inclined to add the options to turn power save off. I have added what I think are the correct module parameters to 88x2bu.conf but have not changed the README pending some testing and feedback.

Your testing and feedback is requested.
