This switches the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5 accordingly. Instead we can do it like other boards already do and simply mux the VSELECT signal of the USDHC interface to the pin. This makes sure that the correct voltage is selected by setting the PMIC's SD_VSEL input to high or low accordingly.
