Interesting, it really looks like the MPC5200 I2C controller.
Unfortunatly :
 - On the MPC5200, all the status/controls bits are in the MSBs ( so
the consts would need to be << 24 )
 - And there is a interrupt control register I don't see in your code.
It's shared by the two I2C controllers onboard.

I'll try to see if I can make it work on the lite5200 board.
