[U-Boot] [PATCH v2 08/13] video: exynos: fimd: add support for various display color modes

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.

Changes v2:
- check panel_info vl_bpix when setting fimd color mode
- move boards configs update to another commit.
