[U-Boot] [PATCH V2 1/2] EXYNOS5: Make all display related code dependent on CONFIG_LCD

[Ajay Kumar]

u-boot compilation fails for smdk5250 when we deselect CONFIG_LCD
from the main config file.

Following error was observed:
drivers/video/libvideo.o: In function `exynos_lcd_init':
/home/ajay/u-boot-samsung/drivers/video/exynos_fb.c:68: undefined reference to `lcd_set_flush_dcache'

This is because exynos video drivers have dependency on CONFIG_LCD.
