[PATCH v2 1/5] drm/encoder_slave: make mode_valid accept const struct drm_display_mode

[Dmitry Baryshkov]

The mode_valid() callbacks of drm_encoder, drm_crtc and drm_bridge
accept const struct drm_display_mode argument. Change the mode_valid
callback of drm_encoder_slave to also accept const argument.
