realtek: add PoE support for GS1920-24HP

Browse source 
Add PoE support for GS1920-24HP by providing the device tree
definition and selecting the Realtek PSE MCU driver package for build.
Support includes both versions of the device since they basically share
the same PSE frontend. The common DTSI includes the shared definitions,
the device DTS files then set the correct compatibles.
