This definitely reduced the occurence rate of this issue, but we still got one of these:

https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4633/fi-glk-j4005/igt@pm_rpm@module-reload.html

Closing anyways because it is so different than the original bug and this issue is anyway covered by https://bugs.freedesktop.org/show_bug.cgi?id=104767.

I haven't even worked out what that test is trying to tell us. If it is just the number of modes, why should they remain constant across runtime-pm; it all depends on the external state coupled with how upset our HW is!
