In order to reuse the FIMC-LITE module on Exynos4 and Exynos5 SoC introduce a set of callbacks for the media pipeline control from within FIMC/FIMC-LITE video node. It lets us avoid symbol dependencies between FIMC-LITE and the whole media device driver, which simplifies the initialization sequences and doesn't introduce issues preventing common kernel image for exynos4 and exynos5 SoCs. This patch also corrects following build errors: drivers/built-in.o: In function `buffer_queue': drivers/media/video/s5p-fimc/fimc-lite.c:414: undefined reference to `fimc_pipeline_s_stream' drivers/built-in.o: In function `fimc_lite_resume': drivers/media/video/s5p-fimc/fimc-lite.c:1518: undefined reference to `fimc_pipeline_initialize' drivers/built-in.o: In function `fimc_lite_suspend': drivers/media/video/s5p-fimc/fimc-lite.c:1544: undefined reference to `fimc_pipeline_shutdown' when only CONFIG_VIDEO_EXYNOS_FIMC_LITE is selected, without CONFIG_VIDEO_S5P_FIMC.
