- Take advantage of mii_phy_dev_probe() and mii_phy_setmedia().
- Set MIIF_NOLOOP as loopback doesn't work with this PHY. The MIIF_NOLOOP
  flag currently triggers nothing but hopefully will be respected by
  mii_phy_setmedia() later on.
- Use MII_ANEGTICKS instead of 5.
- Remove an unused macro.
- Fix some whitespace nits.
