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.

Beata Michalska 94febfb5bc rust: drm: Drop the use of Opaque for ioctl arguments 
With the Opaque<T>, the expectations are that Rust should not
make any assumptions on the layout or invariants of the wrapped
C types. That runs rather counter to ioctl arguments, which must
adhere to certain data-layout constraints. By using Opaque<T>,
ioctl handlers are forced to use unsafe code where none is actually
needed. This adds needless complexity and maintenance overhead,
brining no safety benefits.
Drop the use of Opaque for ioctl arguments as that is not the best
fit here.

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 9a69570682 rust: drm: ioctl: Add DRM ioctl abstraction 
DRM drivers need to be able to declare which driver-specific ioctls they
support. Add an abstraction implementing the required types and a helper
macro to generate the ioctl definition inside the DRM driver.

Note that this macro is not usable until further bits of the abstraction
are in place (but it will not fail to compile on its own, if not called).
