Given that these functions aren't actually hooked up to anything, I'm
not sure if there's any value here.  It sounds like we're going to go to
using the resume_force_mode function for suspend/resume, which means
we'd never use these.

jbarnes: do you like the resume_force_mode plan, or do we want to try to
fix the native suspend/resume stuff?  Should resume_force_mode be safe?
(does it turn off things as necessary for reprogramming if they're
currently on at resume time?)

airlied: do you like the resume_force_mode plan, or do you want to hook
up the save/restore functions so you have an easier time at that hack
you were talking about for user-mode backporting last week?
