Looks good if ibm,current-associativity-domains[min_common_depth]
actually denotes the range of possible values, i.e. a value of 2 implies
node numbers 0 and 1. PAPR+ says it's the "number of unique values",
which isn't how I would specify the property if it's supposed to express
a range. But it's probably OK...
