Subject: new PCI probe code and ASUS AP4

I've noticed that the new PCI probe code doesn't find a PCI bus on my
ASUS PVI-486AP4 (Aries chipset).

The problem is that if out(CONF1_ADDR_PORT, CONF1_ENABLE_CHK), then
inl(CONF1_ADDR_PORT) is equal to CONF1_ENABLE_CHK (not CONF1_ENABLE).

Here is patch that works for me.
