[U-Boot] [PATCH v4 07/12] video: exynos: fimd: add support for various display color modes

[Przemyslaw Marczak]

Now fimd BPP color mode depends on vl_bpp value in struct "panel_info".

There is only 16BPP mode check, default mode is 24BPP.
Other fimd modes are usually unneeded and also needs some fimd driver
modifications and tests.
