So we have a few places where the drm drivers would like to sleep to be nice to the system, mainly in the modesetting paths, but we also have two cases were atomic modesetting must take place, panic writing and kernel debugger. So provide a central inline to determine if a sleep or delay should be used and use this in the intel and radeon drivers.

If MSLEEP is indeed unused, I think it should just die - we have way too much yelling cruft from dri1 yonder lying around that hides important details like this. Otherwise

I've pushed the version that just drops MSLEEP since nobody used it.
Thanks, Dave.
