This commit adds initial device tree support for Rockpro64 board.

generally the patch looks great already. Hopefully we will get an Ack
from the dt-maintaintainers for the binding and I noticed two small
issues I'll describe below.

Rockchip copyright from 2017? Where is the original

Rockpro64 board is similar to firefly rk-3399 board. DTS is taken from firefly board and it is booting fine with minimal changes.

Should I continue with the rockchip rights or update with the mine copy rights?

with recent additions to the pwm-backlight we shouldn't need the
long brightness-levels table and default-brightness-level anymore.
some device support is also needs to be added in this dts. In upcoming patch-sets I will update those changes.
