 this is a nack on my side. the whole i2c has been converted to the
 new style model. everyone is following and this is
 the wrong way to fix the issue.

 the device must be instantiated in the appropriate
 platform code. 

 for an example of what needs to be done, you can grep for
 i2c_board_info in arch/arm .

 if you need help, just tell me where's the acorn related
 platform setup code and I'll have a look.
