Janitorial patch: Removing obsolete, broken oaknet driver including references to it

Hi everybody

As I wandered through the 2.6.14-rc4 kernel I noticed that since 2.6.10 the 
old OAK (PPC403) evaluation board from IBM is no longer supported. I am quite 
familiar with this board, as we at work we have quite a few some running 
another OS.

The ethernet driver for this board (oaknet.c) required quite a few tricks 
(e.g. some function like ei_obp) to work around some very annnoying design 
weaknesses of the original board. As this driver is only used for this board 
and not even compilable (eg. ei_obp is nowhere defined) I think it would be 
better to remove it altogether.

As this is my first attempt to get a patch into the linux kernel, do not 
hesitate to point out any mistakes I made.

My experiences using cogito have been very positive.
