    drm/i915: don't enable self-refresh on Ironlake
    
    We don't know how to enable it safely, especially as outputs turn on and
    off.  When disabling LP1 we also need to make sure LP2 and 3 are already
    disabled.

    drm/i915: Enable self-refresh for Ironlake
    
    We disabled this a while ago as it was inexplicably broken. However, it
    now appears to work...
