dt-bindings: arm: rockchip: Add Edgeble Neural Compute Module 6

Neural Compute Module 6(Neu6) is a 96boards SoM-CB compute module
based on Rockchip RK3588 from Edgeble AI.

Edgeble Neural Compute Module 6(Neu6) IO board is an industrial
form factor evaluation board from Edgeble AI.

Neu6 needs to mount on top of this IO board in order to create complete
Edgeble Neural Compute Module 6(Neu6) IO platform.

This patch add dt-bindings for Edgeble Neu6 Model A SoM based IO board.
