of: address: Fix empty resource handling in __of_address_resource_bounds()
commit 15e2f65f2ecfeb8e39315522e2b5cfdc5651fc10 upstream.
"resource->end" needs to always be equal to "resource->start + size - 1".
The previous version of the function did not perform the "- 1" in case
of an empty resource.
Also make sure to allow an empty resource at address 0.
