sb/intel/bd82x6x/pch: Mark static devices hidden 

Because integrated PCI devices are hidden in chip_ops
the PCI enumeration code never sees them.

When hiding static devices mark them as hidden so the
PCI enumeration no longer complains about them being
missing, even though they are present and were working
just fine.

Test: Disabled southbridge devices no longer appear in
      "Leftover static devices:" log.
