Add a new Kconfig option to enable/disable the extra warnings from the vblank evade code. For now we'll keep the warning about an actually missed vblank always enabled as that can have an actual user visible impact. But if we miss the deadline othrwise there's no real need to bother the user with that. We'll want these warnings enabled during development however so that we can catch regressions.
Based on the reports it looks like this is still very easy to hit on SKL, so we have more work ahead of us to optimize the crtiical section further.
Shouldn't it just be a debug printk or something instead, so that normal people don't see it, but the folks that turn on debugging can get the info they need? Seems silly to add a kconfig option for this.
