Lyude Paul ca57629b3e drm/nouveau/gsp/r570: Enable S/R Display workaround in GSP
There's two flags that we've never been setting when asking GSP to suspend
the GPU, which OpenRM does set:

  GPU_STATE_FLAGS_PRESERVING
  GPU_STATE_FLAGS_PM_TRANSITION

These flags aren't -supposed- to do much in GSP, they're mostly used by
OpenRM itself for state tracking. The only thing they do from GSP's side is
control whether or not a single display related workaround is applied
during suspend.

But as it turns out, that single workaround is actually quite crucial for
getting runtime PM working with nouveau - and without it set we end up
seeing a lot more failures with runtime PM resume. So, let's start setting
it.
