PCI: Export pcie_retrain_link() for use outside ASPM
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.
