Revert "northbridge/intel/peg: Disable unused ports"

This reverts commit 0e06f5bd70b45fd330d8dfb1dc77cce043caf841.

It breaks gm45 and also does some magic without being asked too. It
    disables bridge devices permanently if no device was found on the se-
    condary bus. In a simple notebook world this might be ok, but it breaks
    hot-plugging and late detection (if a secondary bus device comes up too
    slow for the firmware to detect and the OS has to enumerate it).
