dt-bindings: net: ftgmac100: Add resets property

In Aspeed AST2600 design, the MAC internal delay on MAC register cannot
fully reset the RMII interfaces, it may cause the RMII incompletely.
Therefore, we need to add resets property to do SoC-level reset line to
reset the whole MAC function that includes ftgmac, RGMII and RMII.
