[PATCH 10/10] ARM: dts: stm32: add RNG node for STM32MP13x platforms

[Gatien Chevallier]

The RNG on STM32MP13 offers upgrades like customization of its
configuration and the conditional reset.

The hardware RNG should be managed in the secure world for but it
is supported on Linux. Therefore, is it not default enabled.
