Whthout GFX off flag, driver may do gfxhub invalidation before firmware load and gfxhub gart enable. This operation may cause CP to become busy because GC is not in the right state for invalidation. [How] Add a function for SR-IOV to clean up some sw state before recover. Set adev->gfx.is_poweron to false to prevent gfxhub invalidation before gfx firmware autoload complete.
