mb/amd/padmelon: enable PCI device 3.1 for Merlinfalcon
When using a Merlin Falcon APU, explicitly enable the PCIe root port at
B0D3F1. B0D3F0 is only a dummy PCI device function, but needs to also be
enabled in order for the actually used function to be usable. Prairie
Falcon doesn't have and PCI device 3 on bus 0, so remove D3F0 from the
common mainboard devicetree.
