commit fd4e788e971ce763e50762d7b1a0048992949dd0 upstream.
When the SDI output was converted to DRM bridge, the atomic versions of enable and disable funcs were used. This was not intended, as that would require implementing other atomic funcs too. This leads to:
WARNING: CPU: 0 PID: 18 at drivers/gpu/drm/drm_bridge.c:708 drm_atomic_helper_commit_modeset_enables+0x134/0x268
and display not working.
Fix this by using the legacy enable/disable funcs.
