[PATCH 3/5] drm/sti: hda: pass const struct drm_display_mode* to hda_get_mode_idx()

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

Make hda_get_mode_idx() accept 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 accept const
struct drm_display_mode argument.
