drm/i915: Make primary_enabled match the actual hardware state
introduced more accurate tracking of the primary plane and some
checks. It missed the plane->pipe reassignement code for gen2/3
though, which the checks caught and resulted in WARNING backtraces.
Since we only use this path if the plane is on and on the wrong pipe
we can just always set the tracking bit to "enabled".
