drm/debugfs: add a "force" file per connector
Add a file to debugfs for each connector to enable modification of the
"force" connector attribute. This allows connectors to be enabled or
disabled for testing and debugging purposes.
v2: Add stricter value checking and clean up debugfs_entry if file
creation fails in drm_debugfs_connector_add. (David Herrmann)
