ccimx8mn-dvk: add support to apply wifi/bluetooth overlays in the bootscript 

Instead of having two separate device trees for the non-wireless and wireless
variants of the ccimx8mn, use the non-wireless .dtb as a base and apply the
overlays in the bootscript depending on the variant's capabilities.

Also, update the board's device tree list accordingly.
