Carrier board often referred as baseboard. For making
complete SBC, the associated SOM will mount on top of
this carrier board.
Radxa has a carrier board which supports on board
peripherals, ports like USB-2.0, USB-3.0, HDMI, MIPI DSI/CSI,
eDP, Ethernet, PCIe, USB-C, 40-Pin GPIO header and etc.
Currently this carrier board can be used together with
VMARC RK3399Por SOM for making Rock PI N10 SBC.
So add this carrier board dtsi as a separate file in
ARM directory, so-that the same can reuse it in both
arm32 and arm64 variants of Rockchip SOMs.
