Merge tag 'arm-soc/for-5.20/devicetree' of https://github.com/Broadcom/stblinux into arm/dt

This pull request contains Broadcom ARM-based SoCs Device Tree updates
for 5.20, please pull the following:

- Stefan drops the unnecessary "#address-cells" and "#size-cells"
  properties from the DPI node of BCM283x

- Anand documents and adds support for the 63178 and 6858 SoCs

- William migrates the 63138 platform over to ARCH_BCMBCA and ensures
  that it is documented within the BCMBCA Device Tree binding documents.
  He updates the 47622 DTS to remove unnecessary PSCI properties, fix
  the GIC nodes and some minor cosmetic changes. He finally adds support
  for the 63158, 4912, 6846, 6855, 6756, 63146, 6856, 63148, 6813, 6318
  SoCs.

- Peter, Nicolas and Stefan adds the necessary Device Tree nodes to the
  BCM2711 (Raspberry Pi 4) DTS to enable the use of the V3D GPU on these
  platforms.

- Christian adds support for the BCM53015 based Cisco Meraki MR26
  Wi-Fi access point.

- Krzysztof updates the Broadcom platforms DTS to add a missing
  whitespace between the property name and its value.
