If i'm reading the code correct, if this property is missing, the PHY
will fail to probe? Since this was never a mandatory property, it
looks like this will break old DT blobs?

If there are LED properties, then it should be mandatory, otherwise it
should be optional. That way you keep backwards compatibility with old
blobs.
