drm/i915: Constify states passed to enable/disable/etc. encoder hooks
The enable/disable/etc. encoder hooks aren't supposed to alter the state(s), so pass them as const. Unfortunately C lacks any kind of deep const thingy, so this can't catch all abuses. But at least it acts as a hint to the reader telling them not to mess about with the state(s). v2: Update intel_tv_mode_find() and ironlake_edp_pll_on() as well v3: Deal with intel_sdvo_connector_state Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170818134958.15502-9-ville.syrjala@linux.intel.com
