The application circuit shall provide MICVDD power. In default, the codec driver doesn't need to enable LDO2 power. In case, the customers use VBAT for micbias, it should enable the device property "realtek,ldo2-pow-en".
Given that this is just adding a DAPM route I think we can just skip the property and instead simply leave the LDO registered but not connected in the DAPM graph, if a board wants to use it then it can just add a route from the LDO to the relevant input like is currently hard coded in the board file.
