Joachim Wiberg 799fd93cac board/common: fix authorization cascade for internal USB hubs
Two related problems prevented devices behind an intermediate hub (e.g.
the VIA Labs hub on the RPi 400's VL805 xHCI) from being authorized
when confd unlocks a USB bus:

1. Cascade ordering: usb_authorize() ran nftw() with FTW_DEPTH, which
   visits children before the root-hub entry.  The hub was authorized
   while authorized_default was still 2, so when the kernel probed the
   hub's children it immediately denied them.  Fix: write
   authorized_default=1 on the bus before entering nftw.

2. Slow/async probe: hub port enumeration is asynchronous — devices
   behind a hub may appear in sysfs after nftw has already finished.
   Fix: add a udev rule that catches usb_device add events on buses
   where authorized_default=1 is already set on any ancestor root hub
   and authorizes them immediately.

The ATTRS{} matcher in udev walks the full sysfs parent chain, so
authorized_default=1 on the root hub is visible even for devices several
hubs deep.  Buses still locked at authorized_default=0 are left alone.

Also expand the docstring in generic_usb_ports() to document the
design: each root hub gets its own uniquely-named entry (USB, or USB1/
USB2/... when multiple) so buses can be individually controlled, and
boards needing finer control should use DT usb-ports annotations.

Mattias Walström fd38b18bb7 Revert "udev: Always enumerate wifi phys from 0"
This reverts commit bf1eca0567.

This mess up order if having more than 1 phy, have not been
reproduce the error that got me to introduce this fix from
the beginning.

Mattias Walström bf1eca0567 udev: Always enumerate wifi phys from 0
At least RPI4 this enumaration feels pretty random.

Mattias Walström fec018148c Refactor WiFI implementation
* Wi-Fi station still work (changed YANG model)
* Wi-Fi access point supported

Model is flexible to support even more modes

Mattias Walström 915bef2dd4 udev: Rename all wlan interfaces wifiN and start scanning
This since the feature is called 'wifi' in Infix, this makes the naming
consistent over the system.

Also trigger start of a wpa_supplicant, for scanning in the background.
The scanning results is available operational.

Joachim Wiberg fa1cece60f Follow-up to 2194f7be: migrate /libexec to /usr/libexec
For consistency with the / + /usr merge, see 2194f7be, let's move the
last remnants in /: /libexec/infix to /usr/libexec/infix
