NAK because there is already a mechanism that does what you want.  Its
called the aliases node.

For the record, I'm making 2 arguments here:

1) if you *do* need an enumerated index then use the aliases node.
You don't need to invent a new property
2) for i2c purposes, explicit enumeration is not needed or desired.
All the necessary data is already present in the device tree in that
i2c device nodes are children of i2c bus nodes.  The i2c bus numbers
should be dynamically assigned.

Cheers,
