[PATCH] of: When constructing the bus id consider assigned-addresses as well

[Jason Gunthorpe <jgunthorpe@obsidianresearch.com>]

'assigned-addresses' is used for certain PCI device type nodes in
lieu of 'reg',  since this is enforced by of/address.c, have
of_device_make_bus_id look there as well.

of_can_translate_address and of_translate_address already support
using assigned-addresses.
