drm/i915/execlists: Reset RING registers upon resume
commit bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae upstream.
Kernel 4.10 does show the same behaviour.
Please also see the bisect history on github [1] and this forum thread [2].

Expected behaviour: Resuming from suspend to disk normally by displaying lock
screen.
Actual behaviour: System powers on but resumes to a black screen.</pre>
