[ Upstream commit 1badf482816417dca71f8120b4c540cdc82aa03c ]
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.
