In this patch series, we will try to add basic support for
Khadas Edge2 board, currently only UART and eMMC are enabled.
The ethernet connect to Pads expansion board via USB which will need extra
effort, so no ethernet for now.
The first patch introduce a dt-bindings for Edge2 board,
the second patch will add basic device tree.

2.39.2
Edge2 is an ultraslim, credit-card sized ARM PC designed by Khadas.
In this patch, we will add basic device tree support for this board,
Only eMMC, UART are enabled, so it's capable of booting into
a basic linux system from eMMC via serial console.
