[PATCH 3/7] arm: dts: imx8mp-evk: Enable the EQoS ethernet port

[Ye Li]

i.MX8MP EVK has two ethernet ports. Add relevant nodes and properties
for EQoS port to the EVK DTS file.
In -u-boot.dtsi, change the u-boot eqos compatible string, add PHY
reset gpio and remove assigned clocks as not supported in CCF.
