Scott and I looked at this just now, and it doesn't seem to be an easy fix
unless we use of_i2c.c, which seems to be unused currently.  Something about not
being able to get the i2c_adapter structure from its corresponding device_node
struct.

Anyone know when of_i2c.c is going to come "online" replace what's in fsl_soc.c?
