EXYNOS: display 32bpp bitmap TIZEN logo

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.
