On rk3399-roc-pc board a voltage regulator MP8859 from Monolithic Power Systems is used to supply the 12V power line. This delivers 5V as a default value after boot. The voltage is controllable via I2C. Add a basic driver to set and get the voltage of the MP8859 and add a matching node with fixed 12V in the DT of the board.
