[U-Boot] [PATCH 6/7] wandboard: Add FIT image support

[Fabio Estevam <festevam@gmail.com>]

After the transition to DM, only the mx6dl/solo wandboard
is supported.

Add FIT image support so that all the wandboard variants
can be supported, like it was prior to the DM conversion.

Successfully booted Linux on mx6q/solo/qp wandboards.
