Add EQOS GMAC node per Documentation/devicetree/bindings/net/imx-dwmac.txt ,
leave out the nvmem entries as that is not yet available, so the MAC has to
be passed in via DT by the bootloader.

The board has both MACs routed out, enable the EQOS.

V2: - Rebase on latest linux-next
- Move eqos and pinmux entries from imx8mp-phycore-som.dtsi to
imx8mp-phyboard-pollux-rdk.dts, because the PHY is populated
on the baseboard, not on the SoM.
