Subject: [net-next,v1, 0/1] Enable SERDES power up/down

This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal.
1.Introduced 2 new BSP callbacks ->serdes_powerup() and ->serdes_powerdown().
2.The 2 new BSP callbacks is called in stmmac_dvr_probe() and
  stmmac_resume() for SERDER powerup; stmmac_dvr_remove() and
  stmmac_suspend() for SERDES powerdown.
3.Intel platform specific SERDES powerup and powerdown sequence functions
  are added in dwmac-intel.c.
4.Since configuring the SERDES is through mdio, mdio communication is
  needed to be up before powerup sequence. As for SERDES power-down
  sequence, it must be configured after all dma stop and before unregister
  the mdio bus.
5.New file dwmac-intel.h is created for register definition.
