This reverts commit c584a1c7c8a192c13637bc51c7b63a9f15fe6474.

It brings the rust bindings for USB back into the build so that we can
work off of this for future kernel releases.

Pull Char/Misc/IIO/Binder updates from Greg KH:
 "Here is the big set of char/misc/iio and other driver subsystem
  changes for 6.18-rc1.

  Loads of different stuff in here, it was a busy development cycle in
  lots of different subsystems, with over 27k new lines added to the
  tree.

  Included in here are:

   - IIO updates including new drivers, reworking of existing apis, and
     other goodness in the sensor subsystems

   - MEI driver updates and additions

   - NVMEM driver updates

   - slimbus removal for an unused driver and some other minor updates

   - coresight driver updates and additions

   - MHI driver updates

   - comedi driver updates and fixes

   - extcon driver updates

   - interconnect driver additions

   - eeprom driver updates and fixes

   - minor UIO driver updates

   - tiny W1 driver updates

  But the majority of new code is in the rust bindings and additions,
  which includes:

   - misc driver rust binding updates for read/write support, we can now
     write "normal" misc drivers in rust fully, and the sample driver
     shows how this can be done.

   - Initial framework for USB driver rust bindings, which are disabled
     for now in the build, due to limited support, but coming in through
     this tree due to dependencies on other rust binding changes that
     were in here. I'll be enabling these back on in the build in the
     usb.git tree after -rc1 is out so that developers can continue to
     work on these in linux-next over the next development cycle.

   - Android Binder driver implemented in Rust.

     This is the big one, and was driving a huge majority of the rust
     binding work over the past years. Right now there are two binder
     drivers in the kernel, selected only at build time as to which one
     to use as binder wants to be included in the system at boot time.

     The binder C maintainers all agreed on this, as eventually, they
     want the C code to be removed from the tree, but it will take a few
     releases to get there while both are maintained to ensure that the
     rust implementation is fully stable and compliant with the existing
     userspace apis.

  All of these have been in linux-next for a while"

The rust USB bindings as submitted are a good start, but they don't
really seem to be correct in a number of minor places, so just disable
them from the build entirely at this point in time.  When they are ready
to be re-enabled, this commit can be reverted.

In light of the newly-added Rust abstractions for USB devices and
drivers, add a sample USB rust driver that serves both to showcase what
is currently supported, as well as be the only user of the USB
abstractions for now.

[ force USB = y for now - gregkh ]

Adds a new sample driver `rust_scoped_debugfs` that demonstrates the
use of the scoped debugfs APIs.

The driver creates a `control` directory with two write-only files,
`create` and `remove`. Writing a name and a series of numbers to
`create` will create a new subdirectory under a `dynamic` directory.
This new subdirectory will contain files that expose the numbers as
atomic values.

Writing a name to `remove` will remove the corresponding subdirectory
from the `dynamic` directory.

This sample serves as an example of how to use the `debugfs::Scope`
and `debugfs::ScopedDir` APIs to create and manage debugfs entries
that are tied to the lifetime of a data structure.
