Subject: [PATCH v3 3/4] ARM: dts: bcm2835: Move rng definition to common location

BCM2711 inherits from BCM283X, but has an incompatible HWRNG. Move this
node to bcm2835-common.dtsi, so that BCM2711 can define its own.

Signed-off-by: Stephen Brennan <stephen@...nnan.io>
---

Changes in v3:
- moved the bcm2835 rng into bcm2835-common.dtsi rather than a new file
- split out enabling rng on bcm2711 into its own patch
