Add Device Tree hierarchy for Realtek Kent SoC family:
- kent.dtsi: base SoC layer
- rtd<variant>.dtsi: SoC variant layer
- rtd<variant>-<board>.dtsi: board layer
- rtd<variant>-<board>-<config>.dts: board configuration layer
Include RTD1501S Phantom EVB (8GB), RTD1861B Krypton EVB (8GB), and
RTD1920S Smallville EVB (4GB).
