ARM: dts: imx6qdl-icore: Add fec phy-handle
LAN8720 needs a reset of every clock enable. The reset needs
to be done at device level, due the flag PHY_RST_AFTER_CLK_EN.
So, add phy-handle by creating mdio child node inside fec.
This will eventually move the phy-reset-gpio which is defined
in fec node.
