Keep all the platform output selection in intel_output_setup(), and don't
scatter it around. As a useful side effect, do not try to enable LVDS on
HSW or VLV.
Some checks are done in a slightly different order than before, and on some
platforms VGA is now initialized before LVDS.

I took this out of the VLV series to give it the attention it needs.
