faq: add new Wi-Fi card: AsiaRF AW7615-NP1

Currently, I am somehow confused. We label this card as WS3294, which is refered to https://www.asiarf.com/shop/wifi-wlan/wifi_mini_pcie/wifi-mini-pcie-module-mtk-mt7615-4x4-11ac-5g-ws3294-manufacturer/ , but this card is oversized and confirmed also by wikidev. But it should be rather based on the image is: AsiaRF AW7615-NP1.

I'm waiting to get confirmation from HW department. Right now, this is Blocked.
