From a device tree perspective, index and cell-index are both
incorrect.  The IIC macros don't share register blocks with anything,
are enumerated as unique instances per macro in the device tree, and

I think we should just expand the definition of cell-index to include standard
device enumeration for when it's needed.  The original definition is too
limited, IMHO.
