drm/nouveau: Introduce NvPmEnableGating option
This adds the NvPmEnableGating config option to nouveau, which can be used to enable or disable clockgating for supported chipsets. Enabling can be done by passing config=NvPmEnableGating=1 To nouveau. If your chipset supports it, you'll see a message in your kernel log indicating that clockgating is enabled. Since clockgating has only had limited testing thus far, we leave this option disabled by default for now. Signed-off-by:Lyude Paul <lyude@redhat.com> Reviewed-by:
