[PATCH 3/4] rockchip: dts: rk3328: Add rng details to u-boot.dtsi

[Peter Robinson]

Add the rk3328 rng details to the u-boot.dtsi and
enable the RNG on the Rock64 to be able to provide
a rnadom seed via UEFI.

Signed-off-by: Peter Robinson <pbrobinson at gmail.com>

The DT snippet will allow this to be enabled on other rk3328 devices but
I only have the Rock54 to test on.
