A reference to the binding document describing the pin control bindings
would be appropriate here. Given that reference, I'm not sure if
spelling out the property names makes sense since it feels a little like
duplication; an alternative might be simply:

The pinctrl bindings defined in ../../../pinctrl/pinctrl-bindings.txt
must be used to define a pinctrl state named "default".

However, this isn't a big deal; it's fine either way.
