RPi5: wlan0 doesn't exist when Boot Order is USB->SDCARD

[rh1972]

Describe the bug

Using latest bookworm image, via the RPi Imager, the wlan0 interface only exists when Boot Order is SDCARD->USB.
When changing this to USB->SDCARD, it doesn't appear in "ifconfig", nor "rfkill list" and WLAN Locale is greyed out.
Changing back to SDCARD->USB restores the wlan0 interface.

There is no sdcard in slot.

Steps to reproduce the behaviour

1. Burn image to SSD drive via RPi official imager.
2. wlan0 exists, if Boot Order is SDCARD->USB
3. Change Boot Order to USB->SDCARD, wlan0 doesn't exist after boot.
4. Changing it back to SDCARD->USB, wlan0 exists after boot.

Closing, as this perhaps should be under the "firmware" repository.
