ppc4xx: Add AMCC Glacier 406GT eval board support
This patch adds support for the AMCC Glacier 460GT eval board.
The main difference to the Canyonlands board are listed here:
- 4 ethernet ports instead of 2
- no SATA port
- no USB port
Currently EMAC2+3 are not working. This will be fixed in a later
release.
