DRM Rust changes for v6.18

Alloc
  - Add BorrowedPage type and AsPageIter trait
  - Implement Vmalloc::to_page() and VmallocPageIter
  - Implement AsPageIter for VBox and VVec

DMA & Scatterlist
  - Add dma::DataDirection and type alias for dma_addr_t
  - Abstraction for struct scatterlist and struct sg_table

DRM
  - In the DRM GEM module, simplify overall use of generics, add
    DriverFile type alias and drop Object::SIZE.

Nova (Core)
  - Various register!() macro improvements (paving the way for lifting
    it to common driver infrastructure)
  - Minor VBios fixes and refactoring
  - Minor firmware request refactoring
  - Advance firmware boot stages; process Booter and patch its
    signature, process GSP and GSP bootloader
  - Switch development fimrware version to r570.144
  - Add basic firmware bindings for r570.144
  - Move GSP boot code to its own module
  - Clean up and take advantage of pin-init features to store most of
    the driver's private data within a single allocation
  - Update ARef import from sync::aref
  - Add website to MAINTAINERS entry

Nova (DRM)
  - Update ARef import from sync::aref
  - Add website to MAINTAINERS entry

Pin-Init
  - Merge pin-init PR from Benno
    - `#[pin_data]` now generates a `*Projection` struct similar to the
      `pin-project` crate.

    - Add initializer code blocks to `[try_][pin_]init!` macros: make
      initializer macros accept any number of `_: {/* arbitrary code
      */},` & make them run the code at that point.

    - Make the `[try_][pin_]init!` macros expose initialized fields via
      a `let` binding as `&mut T` or `Pin<&mut T>` for later fields.

Rust
  - Various methods for AsBytes and FromBytes traits

Tyr
  - Initial Rust driver skeleton for ARM Mali GPUs.
    - It can power up the GPU, query for GPU metatdata through MMIO and
      provide the metadata to userspace via DRM device IOCTL (struct
      drm_panthor_dev_query).
