[v2,8/9] ARM: meson: dts: add basic Meson/Meson6/Meson6-atv1200 DTSI/DTS

Commit Message

The Meson6 SoC is produced by Amlogic inc. and it is based on 2 Cortex
A9 and an ARM Mali-400 GPU.
This patch adds two basic DTSI for the preliminary support of Meson and
Meson6 SoCs. Another DTS is also added for supporting the atv1200 board,
produced by Geniatech inc.

We recently had a discussion about licensing of dts files. Please make
these dual-licensed GPL+BSD or similar, so they can be included in
other operating systems as well.

I think it would be best to move these aliases into the per-board
file and only list the present ones.
