  Correct endianness handling in getting station address from EEPROM.
  While I'm here, remove aue_eeprom_getword() as its only usage is to
  read station address and make it more readable.  This change is
  inspired by NetBSD.
  With this change, aue(4) should work on big endian architectures.

  Add workaround for MCP61 Ethernet controller found on MSI K9
  motherboard.  PHY hardware used for the controller responded at
  all possible addresses which in turn resulted in having 32 PHYs
  for the controller.  If driver detects "MSI K9N6PGM2-V2 (MS-7309)"
  motherboard, tell miibus(4) PHY is located at 0.
