[PATCH v2 2/6] arm64: dts: rockchip: Mark rock-pi-4 as rock-pi-4a dts

[Jagan Teki]

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

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

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