Stepan: No, the information has to be reorganized. Currently pirq and mptables
Stepan: have to be hand crafted, and this is the complicated thing. Instead the
Stepan: abstract information should be put to the configuration filess, if it 
Stepan: can not be probed.

YH: I suggest to add 
1. one node id to ram_resource, so the index will be (idx<<8 | nodeid), So I can re-use ram_resource in pci_domain for SRAT creating.
2. for apci_cluster_id, will add two fields core_id and node_id, ( instantiate it when cpu_init)...
3. pci device: add pci_irq_routing, and pci_possiable_resource ( for apci _PRT and _PRS...)

how about ioapci in the internal tree?
