[PATCH v2] drm/bridge: lt9611uxc: reset edid_read on disconnect

[Nilesh Laad]

Currently edid_read has value from previous connect session
and resulting in drm using older edid before new edid is available
in lt9611uxc.
Reset edid_read so that correct status is updated and correct edid
is available for drm.
