[U-Boot] [PATCH V4 3/4] video: Modify exynos_fimd driver to support LCD console

[Ajay Kumar]

Currently, exynos FIMD driver is being used to support only TIZEN LOGOs.
In order to get LCD console, we need to enable half word swap feature
of FIMD and use 16 BPP.
LCD console and proprietary Logo cannot be used simultaneously.
We use logo_on field inside vidinfo_t structure to decide whether
user wants Logo or Console.
