Since this is run in the compute config stage we need to check
the new_ pointers, not the current modeset layout. Also there
was a little logic bug in properly skipping connectors. This has
been broken when moving the pipe bpp selection in

drm/i915: precompute pipe bpp before touching the hw
To avoid too much casting switch from drm_ to intel_ types.
Also add a bit of debug output to help reconstructing what's going
on.
