    drm/nouveau/bar/gk20a: Avoid bar teardown during init · e062a01e

    Commit bbb163e1 ("drm/nouveau/bar: implement bar1 teardown")
    introduced add a teardown helper function for BAR1. During
    initialisation of the Nouveau, initially all the teardown helpers are
    called once, before calling their init counterparts. For gk20a, after
    the BAR1 teardown function is called, the device is hanging during the
    initialisation of the FB sub-device. At this point it is unclear why
    this is happening and this is still under investigation. However, this
    change is preventing Tegra124 devices from booting when Nouveau is
    enabled. To allow Tegra124 to boot, remove the teardown helper for
    gk20a.
    
    This is based upon a previous patch by Guillaume Tucker but limits
    the workaround to only gk20a GPUs.
