Myles Watson 267ce7cbf7 This patch should serve as a porting help for other northbridges for the new resource allocator.
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.
