drm/i915: Use connector_type for printing in intel_connector_info, v2.
Instead of looking at encoder->type, which may be set to UNKNOWN, use connector->connector_type. Info cannot be printed for MST connectors which may have a NULL encoder, return early in that case. Changes since v1: - Whitelist encoder types for HDMI and LVDS. - Fix oops on MST. - Do not list encoder types for eDP/DP, they're always valid.
