Turris Omnia WiFi cards dectection sometimes fails

ls: /sys/bus/pci/devices/0000:00:01.0/000*/iee*/phy*: No such file or directory

This happens most likely because wifi cards are not yet detected at time of board script execution.

The /etc/board.d scripts are executed as one of the last steps in preinit but all kernel modules are loaded right after preinit. The drivers are not built in so the devices are just not available.

The result of this is that led for wifi card is just not configured to blink with appropriate device. In effect it is set to not blink at all.

The solution would be to just hardcode there wlan0 for PCI1 led and so on for all PCI leds.

Second option is to simply disable them and add it somehow as part of wifi detection. This would be possibly even better option.

Looking in to upstream not a single one of the targets configures wifi leds in that file (for most likely obvious reasons). We should not do it as well. They do not configure leds in that file at all, they use 01_leds.

Interesting option is to use hotplug to update/set correct device. This could cover not only boot but in general would be much more versatile such as ability to add the same for not only wifi cards but also for drives and such.
