When only DP is used, we need not enable CONFIG_EXYNOS_MIPI_DSIM. But if we do not select CONFIG_EXYNOS_MIPI_DSIM, exynos_fb.c throws error saying exynos_mipi_dsi_init() not defined. So, we add dummy definition for exynos_mipi_dsi_init when CONFIG_EXYNOS_MIPI_DSIM is not defined.
Changes in V2: -- Make dummy definition for exynos_mipi_dsi_init as static. Changes in V3: -- Added Changelog in commit message.
