Looks like all of these are due to missing readout in
i9xx/ilk_get_pipe_config().

The hsw case must be something a bit more subtle since you did add
something to hsw_get_pipe_config(). I can't immediately see what would
cause this. Probably best to fix the other platforms first and get
a new set of results with the extra noise removed, and then we can see
if you hit the same warn on the other platforms as you have on hsw.
