Rock PI 4 has 3 variants of hardware platforms called
RockPI 4A, 4B, and 4C.

- Rock PI 4A has no Wif/BT.
- Rock PI 4B has AP6256 Wifi/BT, PoE.
- Rock PI 4C has AP6256 Wifi/BT, PoE, miniDP, USB Host enable
  GPIO pin change compared to 4B, 4C

So move common nodes, properties into dtsi file and include
on respective variant dts files.
