Somehow I managed to completely miss sending out the first patch here
(thanks Chen Baozi!)...

This should be inserted at the head of the series.

Subject: [PATCH] xen: dt: add dt_translate_address to translate a raw address

A future patch is going to want to translate an address which is not
part of the reg property so the existing dt_device_get_address is not
suitable.

This is the same function as Linux's of_translate_address but with the
names changed to fit our context and the dev parameter constified.
