drm/amdgpu: Partially revert "drm/amdgpu: update drm_display_info correctly when the edid is read"

This partially reverts 20543be.

Calling drm_connector_update_edid_property() in
amdgpu_connector_free_edid() causes a noticeable pause in
the system every 10 seconds on polled outputs so revert this
part of the change.
