EXYNOS: display 32bpp bitmap TIZEN logo

This patch supports drawing 32bpp bitmap TIZEN logo in exynos fb.
"tizen_hd_logo.h" data is compressed from trats_logo.bmp to
trats_logo.bmp.gz by gzip and converted to tizen_hd_logo.h header file
format by some application. The logo data is decompressed in the exynos
fb driver by bmp_display().
