drm/i915/bios: debug log ddi port info after parsing 



The ddc pin and aux channel sanitization may disable DVI/HDMI and DP,
respectively, of ports parsed earlier, in "last one wins" fashion. With
parsing and printing interleaved, we'll end up logging support first and
disabling later anyway.

Now that we've split ddi port info parsing and printing, take it further
by doing the printing in a separate loop, fixing the logging.

Note that this also changes the logging order from VBT child device
order to port number order.
