[PATCH v4 0/2] Rust abstractions for Device & Firmware

[Danilo Krummrich <dakr@redhat.com>]

Hi,

as agreed in [1] this is the separate series for the device and firmware
abstractions to unblock the inclusion of Fujita's PHY driver.

Originally, those patches were part of the patch series [2][3].

Changes in v4
=============
- add invariant of unmodified backing buffer to `Firmware` (Boqun)

Changes in v3
=============
- fix safety comments for `Send` and `Sync` for `Device` (Boqun)
- add corresponding invariant and safety requirement for `Device::from_raw`
  (Boqun)
- drop `Firmware::request_platform` and `Firmware::request_direct` (Greg)
- fix missing Kconfig entry for `Firmware` (Greg)
- fix doctest compilation for `Firmware`

Changes in v2
=============
- use the 'srctree/' notation
- expand the existing documentation and make it more unambiguous
- use `NonNull` in `Firmware`
- generalize the `Firmware` request functions
- add missing safety comments to `Firmware`
