net: stmmac: support fp parameter of tc-mqprio

Browse source 
tc-mqprio can select whether traffic classes are express or preemptible.

After some traffic tests, MAC merge layer statistics are all good.

Local device:
ethtool --include-statistics --json --show-mm eth1
[ {
        "ifname": "eth1",
        "pmac-enabled": true,
        "tx-enabled": true,
        "tx-active": true,
        "tx-min-frag-size": 60,
        "rx-min-frag-size": 60,
        "verify-enabled": true,
        "verify-time": 100,
        "max-verify-time": 128,
        "verify-status": "SUCCEEDED",
        "statistics": {

            "MACMergeFrameSmdErrorCount": 0,
            "MACMergeFrameAssOkCount": 0,

            "MACMergeFragCountTx": 35105,
            "MACMergeHoldCount": 0
        }
    } ]
