[PATCH] Fix wrong /proc/iomem on SGI Altix

[PATCH] Fix wrong /proc/iomem on SGI Altix

In sn_io_slot_fixup(), the parent is re-set from the bus to
io(port|mem)_resource because the address is changed in a way that it's not
child of the bus any more.

However, only the root is set but not the parent/child/sibling relationship
in the resource tree which causes 'cat /proc/iomem' to stop after this
memory area.  Depding on the poition in the tree the iomem may be nearly
completely empty.
