Keep the node disabled as HDP needs the pinctrl SoC configuration to be able to output its mux output signal outside of the SoC, on the SoC pad. This configuration is provided in the board dtsi file through 'pinctrl-*' properties as well as HDP mux configuration. Thus, if needed, HDP should be enabled in board dtsi file.
