[PATCH 8/9] drm/qxl: remove unused debugfs structure

["Maíra Canal" <mcanal@igalia.com>]

The current debugfs structure was introduced at f64122c1f6ad and it was
never used by the driver. Considering the addition of more
device-centered functions to the DRM core, remove the current debugfs
structure.
