Comment # 4 on bug 108575 from Przemek

Yesterday I have observed a strange behavior.

After suspend/resume cycle HDMI screen is turned off, but when you trigger
hibernate/resume after suspend/resume HDMI output is turned back on and is
working properly.
(Yes, hibernation works on CIK and amdgpu now!! Thank you so much!!)

As given above a question arise,
are there other-different triggers/resets in suspend/resume and
hibernate/resume cycles for those asics?

Thanks,
Przemek.
