Subject: [PATCH] ARM64: dts: meson-axg: add ethernet mac controller

Add DT info for the stmmac ethernet MAC which found in
the Amlogic's Meson-AXG SoC, also describe the ethernet
pinctrl & clock information here.

This is tested in the S400 dev board which use a RTL8211F PHY,
and the pins connect to the 'eth_rgmii_y_pins' group.
