[LEDE-DEV] [PATCH] mt7621: add support for WeVO W2914NS v2

[perillamint]

Hi, Mathias Kresin.

It seems its Ethernet LEDs are directly hooked into switch chip. It
flashes without defining them in DTB. I dunno about where WLAN LEDs are
hooked. I failed to drive them with sysfs gpio driver.

I tried LED blinker script in

https://wiki.openwrt.org/doc/hardware/port.gpio

and it only blinked USB LED. So, I added that LED only.

Is there any way to discover how to turn on that two WiFi LEDs?
