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().

Changes for 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.
Changes for v2:
- move fb_rgb_mode_t variable to include/lcd.h
- some bug fixes.
- define CONFIG_TIZEN
- use bmp_display() common display function
Changes for v3:
- use logo resulution variable.
- get logo info through get_tizen_logo_info()
- change draw_tizen_logo() to common draw_logo()
- and so on.
