drm/tyr: Use DRM device type alias across driver

Currently Tyr defines a convenience type alias for its DRM device type,
`TyrDrmDevice` but it does not use the alias outside of `tyr/driver.rs`.

Replace `drm::Device<TyrDrmDriver>` with the alias `TyrDrmDevice` across
the driver.

This change will ease future upstream Tyr development by reducing the
diffs when multiple series are touching these files.

No functional changes are intended.
