One thing I forgot to address was the SOM'nes of the puma board. People
might want to use that with different base-boards so you might want to
split this up into a rk3399-puma-som.dtsi and for example rk3399-puma-haikou.dts
for the Puma + Haikou Q7 combination.

Examples for such a split may be the rk3288-phycore, rk3288-rock2 and
rk3288-firefly-reload.
