If xclk is the name of the pin and you want to mention it, then just:
items:
 - description: xclk clock

(no "reference" or "GPIO descriptor" because it is redundant as Conor wrote)

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
