sh: pci: Support slot 4 routing on SDK7786. SDK7786 supports connecting either slot3 or 4 to the same PCIe port by way of FPGA muxing. By default the vertical slot 3 on the baseboard is enabled, so this adds in a command line option for forcibly enabling the slot 4 edge connector. If nothing has been specified on the command line, we fall back to reading the resistor values for card presence to figure out where to route the port to.
