Add a new "fixed-batteries" DT property to connector class. This
property is populated with nodes associated with battery type power
supplies powering the USB PD connector. This is needed by the Type-C
Port Manager (TCPM) to query psy properties which are used to feed
Battery_Status & Battery_Capacity AMS.
