[U-Boot] [PATCH V2 2/4] EXYNOS: Add dummy definition to fix compilation dependency on CONFIG_EXYNOS_MIPI_DSIM

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.
