mmio 64 allocation that could help Guo Chao <yan@linux.vnet.ibm.com> on powerpc mmio allocation. It will try to assign 64 bit resource above 4g at first.
And it is based on current pci/next and pci/resource.
-v2: update after patch that move device_del down to pci_destroy_dev. add "Try best to allocate pref mmio 64bit above 4G"
-v3: refresh and send out after pci_clip_resource() changes, as Bjorn is not happy with attachments.
-v4: make pcibios_resource_to_bus take bus directly.
-v5: fix non-pref mmio64 allocation problem found by Guo Chao. refresh last three as Bjorn update first two and put them in pci/resource
-v6: try above 4G at first, then restart again for under 4G. so we can drop patch that sort pci root bus resource list.
