file-by-file changes:

dts:
    There are no bus devices, remove it. Add the northbridge devices.
    Fix susbsytem_vendor and subsystem_device.

southbridge/intel/i82371eb/ide:
    Make the ide enabled by default.

northbridge/intel/i440bxemulation/i440bx.c:
    1. Split ops into domain and northbridge
        A. Domain should have bus ops, scan_bus, etc.
        B. Northbridge should have ops for its own registers.
            In this case it only needs read and set resources.

functions:
    i440bx_read_resources - set up the IO and VGA resources. VGA is fixed.
    i440bx_ram_resources - this should be called after resource assignment.
    i440bx_set_resources - call pci_set_resources then i440bx_ram_resources.
    i440bx_domain_read_resources - Set up system-wide resources, and
        reserve space for the local APIC. I put the IOAPIC here too,
        but it belongs somewhere in the southbridge.
    i440bx_domain_set_resources - Mark the domain-specific resources as
        stored (In a real device you'd probably need to set some
        registers here.) Call phase4_set_resources for children.

southbridge/intel/i82371eb/i82371eb.c:
    1. Add ISA read and set resources to reserve legacy IO space.
        - Note that since it's subtractively decoded, it doesn't need
        to be stored anywhere. It needs to be marked stored so
        pci_set_resource doesn't try to store it.
