Kernel is trying to eliminate callers of flush_scheduled_work so lets
try to accommodate.

We currently call it from intel_modeset_driver_remove_noirq on the driver
remove path but the comment next to it does not tell me what exact work it
wants to flush.

I can spot three (or four) works using the system_wq:

  ..hotplug.reenable_work
  ..hotplug.hotplug_work
  ..psr.dc3co_work
  ..crtc->drrs.work

So if I replace it with intel_hpd_cancel_work() that appears would handle
the first two. What about the other two?

I am clueless about the display paths and only send this because Jani
convinced me to send a patch to kick off the discussion. No expectations
whatsoever this is correct or complete.
