Pick up changes from Parag Patel and Kachun Lee, and self:
1. The offsets for some registers change in LIVENGOOD. Gratuitously.
2. Define LIVENGOOD and LIVENGOOD_CU part numbers. Add some more
specific LIVENGOOD defaults.
3. Add definitions for PHY support for the copper LIVENGOOD part
(10/100/1000).
