Well, you only really two have choices:

1) Probe on the AC97/SSI nodes
2) When the driver initializes, just scan all the nodes in the device tree (no 
probing).

I think option #2 makes the most sense, because option #1 says that your fabric 
driver is really an AC97 driver, which it isn't.

You can try to make the fabric driver into a bus driver, but I think that just 
complicates things.
