Subject: [PATCH net-next v3 0/3] Rust abstractions for network PHY drivers

This patchset adds Rust abstractions for phylib. It doesn't fully
cover the C APIs yet but I think that it's already useful. I implement
two PHY drivers (Asix AX88772A PHYs and Realtek Generic FE-GE). Seems
they work well with real hardware.

The first patch introduces Rust bindings for phylib.

The second patch updates the ETHERNET PHY LIBRARY entry in MAINTAINERS
file; adds the binding file and me as a maintainer of the Rust
bindings (as Andrew Lunn suggested).

The last patch introduces the Rust version of Asix PHY drivers,
drivers/net/phy/ax88796b.c. The features are equivalent to the C
version. You can choose C (by default) or Rust version on kernel
configuration.

v3:
  - changes the base tree to net-next from rust-next
  - makes this feature optional; only enabled with CONFIG_RUST_PHYLIB_BINDINGS=y
  - cosmetic code and comment improvement
  - adds copyright
v2: https://lore.kernel.org/netdev/20231006094911.3305152-2-fujita.tomonori@gmail.com/T/
  - build failure fix
  - function renaming
