This fix issue when access config from PCIe switch.
Stratix 10 PCIe controller does not support Type 1 to Type 0 conversion as previous version (V1) does.
The PCIe controller need to send Type 0 config TLP if the targeting bus matches with the secondary bus number, which is when the TLP is targeting the immediate device on the link.
The PCIe controller send Type 1 config TLP if the targeting bus is larger than the secondary bus, which is when the TLP is targeting the device not immediate on the link.
