The DeviceTree files for the Peach Pit and Pi machines have a simplistic model of the connections between the different regulators since not all the tps65090 regulators get their input supply voltage from the VDC. DCDC1-3, LD0-1 and fet7 parent supply is indded VDC but the fet1-6 get their input supply from the DCDC1 and DCDC2 output voltage rails. Update the DeviceTree to better reflect the real connections between tps65090 regulators. Having this information in the DTS is useful since FETs are switches that don't provide an output voltage so the regulator core needs to fetch the FET parent output voltage if the child voltage is queried.
