net: stmmac: Disable ACS Feature for GMAC >= 4
ACS Feature is currently enabled for GMAC >= 4 but the llc_snap status is never checked in descriptor rx_status callback. This will cause stmmac to always strip packets even that ACS feature is already stripping them. Lets be safe and disable the ACS feature for GMAC >= 4 and always strip the packets for this GMAC version.
