We get 1 warning when building kernel with W=1: drivers/gpu/drm/exynos/exynos_dp.c:46:5: warning: no previous prototype for 'exynos_dp_crtc_clock_enable' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'.
