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.

Ley Foon Tan (2):
  PCI: altera: Fix configuration type based on secondary number
  PCI: altera: Remove cfgrdX and cfgwrX
