WLAN has always been pcie_rp5, there is nothing on pcie_rp1. RP5 gets
promoted to function 0 (RP1's function) since no earlier functions are
enabled.
This simplifies later refactoring that will handle the FSP root port
enable flags (which were correctly set already) using the device tree
enables.
Test: Boot librem_13v2 and verify WLAN is enabled.
