[U-Boot] [PATCH v2 3/3] EXYNOS: display 32bpp bitmap TIZEN logo

[Donghwa Lee]

This patches support drawing 32bpp bitmap TIZEN logo in exynos fb.
trats_logo.h data is compressed from trats_logo.bmp to
trats_logo.bmp.gz by gzip and converted to trats_logo.h header file
format by some application. And then it is decomressed at the exynos
fb driver by gunzip_bmp().

change of v1:
 - set CONFIG_SYS_VIDEO_LOGO_MAX_SIZE bigger than BMP header file size.
 - drawing logo when boot_logo_on variable sets in board file.
 - move trats_logo* header file to another patch.
 - set RGB order depending on file format in board file.
 - and so on.
