After r207391, brgphy(4) passes resolved flow-control settings to
parent driver. Use that information to configure flow-control.
One drawback is there is no way to disable flow-control as we still
don't have proper way to not advertise RX/TX pause capability to
link partner. But I don't think it would cause severe problems and
users can selectively disable flow-control in switch port.
