    Notify L2pop driver from update_device_(up|down)

    This patch calls update_port_up and update_port_down inside
    of the l2pop driver directly from update_device_up and
    update_device_down in the ML2 RPC layer. This allows the L2pop
    driver to setup forwarding entries completely independent of
    the port status update events.

    This will allow L2pop to function without requiring the ports to
    transition from ACTIVE->BUILD->ACTIVE every time the agent requests
    device details.

    This will unblock the push notifications work and will additionally
    enable us to remove the update to BUILD status as part of a performance
    improvement backport for bug #1665215.
