Add unified genphy_read_status function for C22 and C45
registers. Instead of having genphy_c22 and genphy_c45 methods, this
unifies genphy_read_status functions for C22 and C45.

Add the unified read/write API for C22 and C45 registers. The
abstractions support access to only C22 registers now. Instead of
adding read/write_c45 methods specifically for C45, a new reg module
supports the unified API to access C22 and C45 registers with trait,
by calling an appropriate phylib functions.

Implement AsRef<kernel::device::Device> trait for Device. A PHY driver

Pull Rust updates from Miguel Ojeda:
"The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn,
this makes the version upgrades way simpler and smaller in the future,
e.g. the latest one in commit 56f64b370612 ("rust: upgrade to Rust
1.78.0").
More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a
minimum version in the near future.
Toolchain and infrastructure:
- Upgrade to Rust 1.78.0
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove
one more unstable feature ('offset_of') from the list, among other
improvements
- Drop 'alloc' in-tree fork of the standard library crate, which
means all the unstable features used by 'alloc' (~30 language ones,
~60 library ones) are not a concern anymore
- Support DWARFv5 via the '-Zdwarf-version' flag
- Support zlib and zstd debuginfo compression via the
'-Zdebuginfo-compression' flag
'kernel' crate:
- Support allocation flags ('GFP_*'), particularly in 'Box' (via
'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as
in the 'init' module APIs
- Remove usage of the 'allocator_api' unstable feature
- Remove 'try_' prefix in allocation APIs' names
- Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
fork
- Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'
- Add the 'as_ptr' method to 'ThisModule'
- Add the 'from_raw' method to 'ArcBorrow'
- Add the 'into_unique_or_drop' method to 'Arc'
- Display column number in the 'dbg!' macro output by applying the
equivalent change done to the standard library one
- Migrate 'Work' to '#[pin_data]' thanks to the changes in the
'macros' crate, which allows to remove an unsafe call in its 'new'
associated function
- Prevent namespacing issues when using the '[try_][pin_]init!'
macros by changing the generated name of guard variables
- Make the 'get' method in 'Opaque' const
- Implement the 'Default' trait for 'LockClassKey'
- Remove unneeded 'kernel::prelude' imports from doctests
- Remove redundant imports
'macros' crate:
- Add 'decl_generics' to 'parse_generics()' to support default
values, and use that to allow them in '#[pin_data]'
Helpers:
- Trivial English grammar fix
Documentation:
- Add section on Rust Kselftests to the 'Testing' document
- Expand the 'Abstractions vs. bindings' section of the 'General
Information' document"

Rust's `unused_imports` lint covers both unused and redundant imports.
In the upcoming 1.78.0, the lint detects more cases of redundant imports
[1], e.g.:
error: the item `bindings` is imported redundantly
--> rust/kernel/print.rs:38:9
|
38 | use crate::bindings;
| ^^^^^^^^^^^^^^^ the item `bindings` is already defined by prelude
Most cases are `use crate::bindings`, plus a few other items like `Box`.
Thus clean them up.
Note that, in the `bindings` case, the message "defined by prelude"
above means the extern prelude, i.e. the `--extern` flags we pass.

with `O=` builds:
//! C headers: [`include/linux/phy.h`](../../../../../../../include/linux/phy.h).
This updates such links by using the `srctree`-relative link feature

This macro creates an array of kernel's `struct phy_driver` and
registers it. This also corresponds to the kernel's
`MODULE_DEVICE_TABLE` macro, which embeds the information for module
loading into the module binary file.
A PHY driver should use this macro.

This patch adds abstractions to implement network PHY drivers; the
driver registration and bindings for some of callback functions in
struct phy_driver and many genphy_ functions.
This feature is enabled with CONFIG_RUST_PHYLIB_ABSTRACTIONS=y.
This patch enables unstable const_maybe_uninit_zeroed feature for
kernel crate to enable unsafe code to handle a constant value with
uninitialized data. With the feature, the abstractions can initialize
a phy_driver structure with zero easily; instead of initializing all
the members by hand. It's supposed to be stable in the not so distant
future.
