[PATCH net-next] dt-bindings: net: bluetooth: qualcomm: document VDD_CH1

[Krzysztof Kozlowski]

WCN3990 comes with two chains - CH0 and CH1 - where each takes VDD
regulator.  It seems VDD_CH1 is optional (Linux driver does not care
about it), so document it to fix dtbs_check warnings like:

  sdm850-lenovo-yoga-c630.dtb: bluetooth: 'vddch1-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
