x86 pci: remove checking type for mmconfig probe
doesn't need to check if it is type1 or type2, we can use raw_pci_ops directly. also make pci_direct_conf1 static again. anyway is there system with type 2 and mmconf support? Signed-off-by: Yinghai Lu <yinghai.lu@sun.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
