Subject: [PATCH 0/4] Rust: Fix typedefs for resource_size_t and phys_addr_t

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.

Alice Ryhl (4):
      rust: io: define ResourceSize as resource_size_t
      rust: io: move ResourceSize to top-level io module
      rust: scatterlist: import ResourceSize from kernel::io
      rust: io: add typedef for phys_addr_t
