drm/exynos: constify exynos_drm_crtc_ops structures

Declare exynos_drm_crtc_ops structures as const as they are only passed
as an argument to the function exynos_drm_crtc_create. This argument is
of type const struct exynos_drm_crtc_ops *, so exynos_drm_crtc_ops
structures having this property can be declared const.
Done using Coccinelle:
