[GIT PULL] DRM Rust changes for v7.0-rc1

["Danilo Krummrich" <dakr@kernel.org>]

Hi Dave and Sima,

Please pull these DRM Rust changes.

Most changes have been in -next for a couple of rounds; there's one minor
conflict with the drm-misc tree [1] due to a Panthor/Tyr UAPI change.

In general, there are not a lot of changes this cycle, the biggest thing is the
preparation work for Turing support, but even this is rather small.

Expect quite a bit more for the next cycle, e.g. GPUVM, DRM buddy, DeviceContext
for DRM devices and Hopper/Blackwell support plus some MM stuff on the nova-core
side.

DRM Rust changes for v7.0-rc1

DRM:
  - Fix documentation for Registration constructors.
  - Use pin_init::zeroed() for fops initialization.
  - Annotate DRM helpers with __rust_helper.
  - Improve safety documentation for gem::Object::new().
  - Update AlwaysRefCounted imports.

MM:
  - Prevent integer overflow in page_align().

Nova (Core):
  - Prepare for Turing support. This includes parsing and handling
    Turing-specific firmware headers and sections as well as a Turing
    Falcon HAL implementation.
  - Get rid of the Result<impl PinInit<T, E>> anti-pattern.
  - Relocate initializer-specific code into the appropriate initializer.
  - Use CStr::from_bytes_until_nul() to remove custom helpers.
  - Improve handling of unexpected firmware values.
  - Clean up redundant debug prints.
  - Replace c_str!() with native Rust C-string literals.
  - Update nova-core task list.

Nova (DRM):
  - Align GEM object size to system page size.

Tyr:
  - Use generated uAPI bindings for GpuInfo.
  - Replace manual sleeps with read_poll_timeout().
  - Replace c_str!() with native Rust C-string literals.
  - Suppress warnings for unread fields.
  - Fix incorrect register name in print statement.
