Detecting the smbus is the bit I'm not so clear about; all we have is an OFW
node for the PMU on the PCI bus... 

I guess I could always look for the "i2c" child node directly in
device_register() and call of_enter_i2c_devs() on it, but the thing I'm
not sure if is the code that's there was written that way because there
are HW configurations where the iic devices do hang directly off the OFW
parent of the IIC bus...
