Re: [PATCH 1/2] of: address: Fix empty resource handling in __of_address_resource_bounds()

"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.
