stmmac: dwmac-rk: turn resume/suspend into standard PM callbacks
Use standard PM resume/suspend callbacks instead of the hooks in stmmac_platform. This gives the driver more control and flexibility when implementing PM functionality. The hooks in stmmac_platform also doesn't buy us anything extra. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
