Fix MMCONF_SUPPORT_DEFAULT for ramstage
Define at one place whether to use IO 0xcf8/0xcfc or MMIO via MMCONF_BASE_ADDRESS for PCI configuration access funtions in ramstage. The implementation of pci_default_config() always returned with pci_cf8_conf1. This means any PCI configuration access that did not target bus 0 used PCI IO config operations, if PCI MMIO config was not explicitly requested.
