The unit address has no special meaning for the device tree it's just a
way to give a unique name to a node right?

So in this case it is not really a problem, but it's just nicer for the
coherency of the information in the dt to have the unit address which match
the starting address.

I also do a make dtbs ans I didn't get any errors:
$ make dtbs
 [...]
  DTC     arch/arm/boot/dts/kirkwood-openblocks_a6.dtb
  DTC     arch/arm/boot/dts/kirkwood-openblocks_a7.dtb
