PCI/DPC: Use the generic pcie_do_fatal_recovery() path
Our goal is to handle ERR_FATAL errors similarly, whether they are reported via AER or via DPC. A previous commit changed AER so it handles ERR_FATAL by calling driver .remove() methods and resetting the Link. DPC already does that (although the Link reset is done automatically by hardware and happens before we call the driver .remove() methods). Restructure the DPC code so it calls the same pcie_do_fatal_recovery() interface used by AER. This makes it clearer that we want to use the same path. Implement the .reset_link() method used by pcie_do_fatal_recovery(). For DPC, the actual reset is done automatically by hardware, so we really only have to wait for the Link to be inactive, then release the Port from DPC.
