I have no idea what this means or how one would pick the number?  It
looks like something purely internal to the driver...

Actually it's quite common when we have several HW blocks of the
same thing to add something like an id. For example for different
GPIO banks.

That's common but having the number be in the device tree as a property
or referenced by anything like this isn't common - usually it's just in
the node name if it appears in the DT at all.
