drm/xe: Make wedged_mode debugfs writable

Browse Source 
The intent of this debugfs entry is to allow modification of wedging
behavior, either from IGT tests or during manual debug; it should be
marked as writable to properly reflect this.  In practice this hasn't
caused a problem because we always access wedged_mode as root, which
ignores file permissions, but it's still misleading to have the entry
incorrectly marked as RO.
