Rock Pi N8 is a Rockchip RK3288 based SBC, which has
- VMARC RK3288 SOM (as per SMARC standard) from Vamrs.
- Compatible carrier board from Radxa.

VAMRC RK3288 SOM need to mount on top of radxa dalang
carrier board for making Rock Pi N8 SBC.

So, add initial support for Rock Pi N8 by including rk3288,
rk3288 vamrc-som and raxda dalang carrier board dtsi files.
