drm/sti: hda: pass const struct drm_display_mode* to hda_get_mode_idx() 

Make hda_get_mode_idx() take a const struct drm_display_mode pointer
instead of just raw struct drm_display_mode. This is a preparation to
converting the mode_valid() callback of drm_connector to take a const
struct drm_display_mode argument.
