[TESTME]asrock/e350m1: 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 (i.e. AMD HD6670) has been plugged in to E350M1 board.
It does not bring any downsides if there is no discrete VGA adapter.
