of: address: Unify resource bounds overflow checking
The members "start" and "end" of struct resource are of type
"resource_size_t" which can be 32bit wide.
Values read from OF however are always 64bit wide.
Refactor the diff overflow checks into a helper function.
Also extend the checks to validate each calculation step.
