[TESTME]asus/f2a85-m: fix the VGA-related PCI resource allocation problems
This workaround helps to avoid the PCI resource allocation problems which happen if a discrete VGA adapter has been plugged in to a board of F2A85-M family. It does not bring any downsides if there is no discrete VGA adapter.
