But that's not how compatible properties work -- they should not
contain wildcards. If you have different devices that are
backwards compatible, you should list the older one in all
newer devices, e.g. the 440 can list that it is compatible
with both ibm,405-iic and ibm,440-iic. If there was an earlier
401 that had iic as well, you may even want to include that
in the device tree.
