    drm: remove the EDID blob stored in the EDID property when it is disconnected
    
    Now the EDID property will be updated when the corresponding EDID can be
    obtained from the external display device. But after the external device
    is plugged-out, the EDID property is not updated. In such case we still
    get the corresponding EDID property although it is already detected as
    disconnected.
