PCI ops: MMCONF_SUPPORT_DEFAULT is required

Doing PCI config operations via MMIO window by default is a
    requirement, if supported by the platform. This means chipset
    or CPU code must enable MMCONF operations early in bootblock
    already, or before platform-specific romstage entry.

Platforms are allowed to have NO_MMCONF_SUPPORT only in the
    case it is actually not implemented in the silicon.
