soc/intel/xeon_sp: Redesign resource allocation

The xeon_sp code worked around the coreboot allocator rather than using
it. Now the allocator is able to deal with the multiple IIOs so this is
not necessary anymore.

Instead do the following:
- Parse the FSP HOB information about IIO into coreboot PCI domains
- Use existing scan_bus and read_resource
- Handle IOAT stacks with multiple domains in soc-specific code
