[PATCH v2 1/2] dt-bindings: hwmon: pmbus: ti,lm25066: add current limit properties

[Potin Lai]

Add a 'ti,current-limit' string property to configure the device's Current
Limit (CL) behavior to "high" or "low".

LM25056 does not support setting the current limit via software, so
disallow this property for it.
