Lyude Paul 6ad005ce69 rust/drm: Remove imports covered by prelude::* 
This just removes any explicit imports of items in files that are already
being pulled in by `use prelude::*;`.

There should be no functional changes in this patch.

Miguel Ojeda c2783c7cfe rust: drm: fix srctree/ links 
These `srctree/` links pointed inside `linux/`, but they are directly
under `drm/`.

Thus fix them.

This cleans a future warning that will check our `srctree/` links.

Alice Ryhl 917b10d909 drm: rust: rename as_ref() to from_raw() for drm constructors 
The prefix as_* should not be used for a constructor. Constructors
usually use the prefix from_* instead.

Some prior art in the stdlib: Box::from_raw, CString::from_raw,
Rc::from_raw, Arc::from_raw, Waker::from_raw, File::from_raw_fd.

There is also prior art in the kernel crate: cpufreq::Policy::from_raw,
fs::File::from_raw_file, Kuid::from_raw, ARef::from_raw,
SeqFile::from_raw, VmaNew::from_raw, Io::from_raw.

Asahi Lina a98a73be9e rust: drm: file: Add File abstraction 
A DRM File is the DRM counterpart to a kernel file structure,
representing an open DRM file descriptor.

Add a Rust abstraction to allow drivers to implement their own File types
that implement the DriverFile trait.

[ Rework of drm::File
    * switch to the Opaque<T> type
    * fix (mutable) references to struct drm_file (which in this context
      is UB)
    * restructure and rename functions to align with common kernel
      schemes
    * write and fix safety and invariant comments
    * remove necessity for and convert 'as' casts
