Subject: [PATCH v2 0/3] Support exporting SoC info from Rust

This is a fairly straightforward binding of `soc_device_register` and
`soc_device_unregister` which allows a driver to export basic info about
a SoC.

The last patch is a sample demonstrating usage, and can be dropped
without issue.

Changes in v2:
- Switch to new import style
- Increased documentation. Some of this had to be gathered by looking at
  what is done in practice at the moment, as documentation was absent or
  did not match code.
- Remove `Device` intermediate abstraction
- Removed unnecessary pinning of `BuiltDeviceAttributes` - it only needs
  to be pinned for registration, not to exist.
- Aesthetic renames (`Attributes` pluralization, dropping `Device`,
  etc.)
- Use more representative values for attributes in the sample driver
- Fix swap of example values in the documentation for machine vs family
- Link to v1: https://lore.kernel.org/r/20251212-soc-bindings-v1-0-db51044ce805@google.com
