Merge tag 'arm-soc/for-6.14/devicetree-arm64' of https://github.com/Broadcom/stblinux into soc/dt

This pull request contains Broadcom ARM64-based SoCs Device Tree updates
for 6.14:

- Dave adds the display pipeline DT nodes on BCM2712 (Raspberry Pi 5)

- Rob removes some undocumented properties

- Same ensures that the CFE stub area is reserved to allow secondary
  CPUs to be successfully brought up in Linux, also making sure that the
  address used in the spin table is also carved out. Finally he adds
  support for the Zyxel EX3510-B router using BCM4906

- Rosen converts the BCM4908 platforms to use the more flexible
  nvmem-layout representation
