drm/msm/dp: clear EDID on display unplug

Browse source

Currently the driver only updates the EDID when it detects a connected
monitor, which results in the connector still listing outdated modes
even after the display is unplugged. Set connector's EDID to NULL on
unplug to clear the list of modes.
