    mediatek: remove obsolete patch
    
    The patch enabling hardware flow offloading support on the MT7623 SoC
    has been merged upstream as of Linux 5.13. Remove our local patch which
    wrongly got forward-ported and now actually enables hardware flow
    offloading for the MT2701 SoC family (unsupported in OpenWrt).
