drm/edid: abstract debugfs override EDID set/reset
Add functions drm_edid_override_set() and drm_edid_override_reset() to
support "edid_override" connector debugfs, and to hide the details about
it in drm_edid.c. No functional changes at this time.
Also note in the connector.override_edid flag kernel-doc that this is
only supposed to be modified by the code doing debugfs EDID override
handling. Currently, it is still being modified by amdgpu in
create_eml_sink() and handle_edid_mgmt() for reasons unknown. This was
added in commit 4562236b3bc0 ("drm/amd/dc: Add dc display driver (v2)")
and later moved to amdgpu_dm.c in commit e7b07ceef2a6 ("drm/amd/display:
Merge amdgpu_dm_types and amdgpu_dm").
