Danilo Krummrich f1b55db08d rust: device: fix unresolved link to drm::Device ...

drm::Device is only available when CONFIG_DRM=y, which we have to
consider for intra-doc links, otherwise the rustdoc make target produces
the following warning.

>> warning: unresolved link to `kernel::drm::Device`
   --> rust/kernel/device.rs:154:22
   |
   154 | /// [`drm::Device`]: kernel::drm::Device
   |                      ^^^^^^^^^^^^^^^^^^^ no item named `drm` in module `kernel`
   |
   = note: `#[warn(rustdoc::broken_intra_doc_links)]` on by default

Fix this by making the intra-doc link conditional on CONFIG_DRM being enabled.
