[U-Boot] [PATCH v5] Add support for the digsy MTC board.

[U-Boot] [PATCH v5] Add support for the digsy MTC board.

[Grzegorz Bernacki]

This is the InterControl custom device based on the MPC5200B chip.

Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
---
Version 5:
 - removed unnecessary braces
 - changed out32/in32 to out_be32/in_be32
Version 4:
 - rebased to Ben's FEC changes
Version 3:
 - updated (c)
Version 2:
 - use I/O accessor functions instead of volatile pointer
 - set ethernet address only if not set in environment
 - add some comments and some style cleanup
