In current driver, MAC will always enable 2ns delay in RGMII mode,
but that will lead to transmission failures for "rgmii-id"/"rgmii-txid"
cases.
Modify the implementation of fix_mac_speed() to ensure the 2ns delay
will only take effect for "rgmii-rxid"/"rgmii" cases, then user can
choose phy-mode freely.
