Subtest fade_with_dpms failed.

Despite having the same signature as https://bugs.freedesktop.org/show_bug.cgi?id=107768, it is not the same bug (this issue got introduced 2 drmtip runs after 107768 got fixed).

    igt/pm_backlight: Skip if pm is not supported
    
    If we cannot do runtime suspend, testing it's impact on the backlight is
