drm/debugfs: add an "edid_override" file per connector
Add a file to debugfs for each connector to allow the EDID to be
overridden.
v2: Copy ubuf before accessing it and reject invalid length data. (David
Herrmann)
Ensure override_edid is reset when a new EDID value is written.
(David Herrmann)
Fix the debugfs file permissions. (David Herrmann)
