PCI: Export pcie_retrain_link() for use outside ASPM

Browse source

Export pcie_retrain_link() for link retrain needs outside ASPM.  Struct
pcie_link_state is local to ASPM and only used by pcie_retrain_link() to
get at the associated PCI device, so change the operand and adjust the lone
call site accordingly.  Document the interface.  No functional change at
this point.
