[PATCH 2/2] dt-bindings: pinctrl: amlogic,meson8-pinctrl-cbus: add reg for cbus pinctrl nodes

[Neil Armstrong <neil.armstrong@xxxxxxxxxx>]

While converting the Amlogic Meson pinctrl binding to dt-schema, the mandatory
reg property for Meson8/b cbus pinctrl node was ommited, fix this to finally
pass all bindings checks.
