This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 5.16, please pull the following:

- Matthew provides a set of updates to the Northstar Plus Device Tree
files to fix a number of warnings, and prepare the files to support the
addition of the Cisco Meraki MX64/MX65 wireless controller devices and
finally adds support for those boards.

- Rafal continues to provide updates to the BCM5301X Device Tree files
in order to fix warnings with the various node names, MDIO muxes and
memory nodes. He also adds support for the external switches on the
BCM53573 SoC and adds Tenda AC9 switch ports.

- Christian provides the description of the Ethernet switch ports for
the Cisco Meraki MR32 based on the 53016 SoC

- Arinc adds support for the Asus RT-AC88U device based on the BCM4709
and featuring 8 Ethernet ports over the integrated and the external
Realtek switch (not supported yet)

- Stefan adds support for the Raspberry Pi Compute Module 4 IO board and
does a number of preparatory changes to get there to the Device Tree
files before doing the actual addition
