rockchip: px30: add support for HW RNG for Odroid Go Advance
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. Signed-off-by: Chris Morgan <macromorgan@hotmail.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
