This changes ResourceSize to use the resource_size_t typedef (currently ResourceSize is defined as phys_addr_t), and moves ResourceSize to kernel::io and defines PhysAddr next to it. Any usage of ResourceSize or bindings::phys_addr_t that references a physical address is updated to use the new PhysAddr typedef.
I included some cc stable annotations because I think it is useful to backport this to v6.18. This is to make backporting drivers to the 6.18 LTS easier as we will not have to worry about changing imports when backporting.
