intel_mmio: Add intel_register_access_needs_fakewake

Browse Source 
I screwed this up in my recent patch:
commit c7b6ec50007e2e524a208572c34faf1380eeab1b
Author: Ben Widawsky <ben@bwidawsk.net>
Date:   Wed Apr 24 19:05:18 2013 -0700

    clean warnings: Silence unused (or private) functions

I've clarified the functions now, and added the proper call from the
python script.

Time to get a regression tester for our tools?
