pcengines/apu1: Fix 0:15.x PCIe root ports

Change gpp_configuration to GPP_CFGMODE_X1111 (was X4000), this is done
to only advertise x1 lane width for PCIe link 0:15.0.

Hide functions of PCIe links that have no slots connected. Our PCI
infrastructure does not support bridge devices that are set off
in devicetree but remain visible in the PCI hardware tree.
