[PATCH mt76-next 3/9] wifi: mt76: mt7996: set EHT max ampdu length capability

From: Peter Chiu <chui-hao.chiu at mediatek.com>

Set the max AMPDU length in the EHT MAC CAP. Without this patch, the
peer station cannot obtain the correct capability, which prevents
achieving peak throughput on the 2 GHz band.
