The RK3308 SoC contain a crypto engine block that can generate random
numbers.
Add rng node to soc u-boot.dtsi and enable Kconfig options to take
advantage of the random generator.

Downstream says something different:

I couldn't quickly find the TRM for the RK3308 so cannot check myself
:/
The RK3308 TRM can be found on the link below. BTW, there's also
a rather interesting PDF file that describes a node shrink of the
RK3308, the so-called S-version chip.

Also seems to be missing clocks and resets?
