The "ldo-io0" and "ldo-io1" regulators are enabled/disabled by toggling the pinmux between two functions. This happens in the regulator driver. Setting the pinmux to "ldo" in the DT is inappropriate because it would enable the regulator before the driver has a chance to set the correct initial voltage.
