Introduce MII_ADDR_BASE option on ARM, which allows to override the default

per platform requirements.

Notes:
- Only used by mge(4) at the moment.

- This is very simplified approach and should be replaced by some long-term
  solution for managing the board/platform configuration (among others the
  MAC-PHY binding info).
