i2c-ibm_iic: Register child nodes

Browse Source 
This patch completes the conversion of the IBM IIC driver to an
of-platform driver.

It removes the index from the IBM IIC driver and makes it an unnumbered
driver. It then calls of_register_i2c_devices to properly register all
the child nodes in the DTS.
