Merge tag 'arm-soc/for-6.12/devicetree' of https://github.com/Broadcom/stblinux into soc/dt

This pull request contains Broadcom SoCs Device Tree changes for 6.12,
please pull the following:

- Krzysztof documents the AVS monitor binding present on 2711 (Raspberry
  Pi 4)

- Rafal updates the Broadcom Northstar DTS files to use the recent NVMEM
  binding

- Artur factors the nodes between the BCM21664 and BCM23550 SoCs since
  they are nearly identical

- Stefan converts the bcm2835-system-timer and bcm2836-l1-intc to a YAML
  binding syntax
