net: smsc911x: switch to new dev_pm_ops
Hibernation is unsupported for now, which meets the actual implementation in the driver. For free/thaw, the chip's D2 state should be entered. Signed-off-by: Daniel Mack <daniel@caiaq.de> Acked-by: <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>
