drm/exynos: Fix return type for mixer_mode_valid and hdmi_mode_valid
The field mode_valid in exynos_drm_crtc_ops is expected to be of type enum
drm_mode_status (*mode_valid)(struct exynos_drm_crtc *crtc,
const struct drm_display_mode *mode);
Likewise for mode_valid in drm_connector_helper_funcs.
The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.
The return type of mixer_mode_valid and hdmi_mode_valid should be changed
from int to enum drm_mode_status.
