Document devicetree's binding for the Kizbox2-2 board of
Overkiz SAS based on SAMA5D31 SoC.
Signed-off-by: Kamel Bouhara <[email protected]>
---
Changes in v2:
- Removed other kizbox2 boards as the main difference between
them is the usart configuration, only add the two heads variant
for now.

There are several boards available depending on the PCB
(3 antennas support and several revison). Add a dtsi file to share
common binding between all kizbox2 boards. This patch also add support
for the kizbox2-2 variant.
