cover Introduce new DT files for Meson-AXG SoC

This attempt will try to add new DT files to support Meson-AXG SoC. Due to the AXG series has new memory layout, we decide to start a new DT structure without sharing with previous meson-gx.dtsi

1) in the first patch, we try to document the new Meson-AXG bindings
2) in the second patch, we try to bring up a minimal serial console, so it's capable of running a minimal system (in ramdisk).

PATCH 2/2 arm64: dts: meson-axg: add initial A113D SoC DT support

In reply to Yixun Lan

Try to add basic DT support for the Amlogic's Meson-AXG A113D SoC, which describe components as follows: Reserve Memory, CPU, GIC, IRQ, Timer, UART. It's capable of booting up into the serial console.
