video: s3c-fb: use ARCH_ dependancy

This patch uses ARCH_ dependancy when using s3c-fb.
S3C_DEV_FB, S5P_DEV_FIMD0 cannot be enabled on EXYNOS5.
So, ARCH_ should be used as dependancy for s3c-fb.

video: s3c-fb: remove duplicated S3C_FB_MAX_WIN

S3C_FB_MAX_WIN is already defined in 'plat-samsung/include/plat/fb.h'.
So, this definition in 'include/video/samsung_fimd.h' should be
removed to avoid the duplication.
