Subject: [PATCH] pci: do not export pci_bus_reset

qbus_reset_all can be used instead.  There is no semantic change
because pcibus_reset returns 1 and takes care of the device
tree traversal.

This will be necessary once the traversal is done always in
qbus_reset_all *before* invoking pcibus_reset itself.
