[PATCH 05/14] drm: properly init/reset connector status

[Daniel Vetter]

We need this because otherwise the improved connector code has no idea
when it needs to run the ->detect callback after boot/resume on all
connectors.

Because drm/i915 is the only driver that properly calls
mode_config_reset at resume time, this will horribly blow up
everywhere else.
