rockchip: px30: add support for HW RNG for Odroid Go Advance

Browse source 
The Odroid Go Advance has a hardware random number generator present.
The device does not have an upstream Linux driver, but does have a
U-Boot driver. Add the appropriate node so that the hardware RNG can be
used in U-Boot.
