PCI: altera: Fix configuration type based on secondary number
Stratix 10 PCIe controller does not support Type 1 to Type 0 conversion as previous version (V1) does so the PCIe controller configuration mechanism needs to send Type 0 config TLP if the target bus number matches with the secondary bus number. Implement a function to form a TLP header that depends on the PCIe controller version, so that the header can be formed according to specific host controller HW internals, fixing the type conversion issue.
