net: ethernet: mtk_wed: fix loading WO firmware for MT7986

Browse Source 
MT7986 requires a different mask for second WO firmware.
Without this, WO would timeout after loading FW.

The correct mask was removed when adding WED for MT7988.
Add it back and add a WED version check to fix it.

This can be reproduced with a MT7986 + MT7916 board.
