ieee1394: extend lowlevel API for address range properties
Host adapter hardware imposes certain restrictions and features on address ranges. Instead of hard-wire such ranges into the ieee1394 core or even into protocol drivers, let lowlevel drivers specify these ranges via struct hpsb_host. Patch "ohci1394: set address range properties" must be applied too, else hpsb_allocate_and_register_addrspace() won't work properly.
