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.
