Since i2c probing is hit and miss at best; Most MPCxxxx SPI busses get
the i2c bus topology out of the device tree file
(arch/powerpc/boot/dts/<board-name>.dts) and do not support probing.
If the i2c device you need is missing, then add a node to the .dts
file for the missing device (there are lots of examples of this in the
dts directory).
