There is not known root cause to why we end up in a situation
where the dmc doesn't anymore obey us on dc state setup.


But here are few patches to alleviate the consequences
if that happens. We really want to keep the gpu alive
even if the dmc starts hallucinating.

Mika Kuoppala (2):
  drm/i915: Stop using DC states if firmware disagrees on the state
  drm/i915: Use init power domain during reset
