Some Ethernet PHYs (like marvell10g) will decide the host interface mode by the media-side speed. So, the rswitch driver needs to initialize one of the Ethernet SERDES (r8a779f0-eth-serdes) ports after linked the Ethernet PHY up. The r8a779f0-eth-serdes driver has .init() for initializing all ports and .power_on() for initializing each port. So, add phy_power_{on,off} calling for it.
