wifi: mt76: mt7925: support new WoW pattern TLV

Browse Source 
Newer mt7925 firmware uses a shorter WoW pattern TLV with rsv[3]. Select
the v2 layout based on the firmware build date, while keeping the old
layout for older firmware.

This also makes the WoW pattern handling compatible with newer devices
such as MT7928.
