The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures.
