Currently, any edids read by the driver are cached in the
sde_connector object. In the event that subsequent edids are written,
the cached edid is used instead of the newly written edid.
In the event a new edid is written to the edid debugfs node over
dpsim, this change clears the current cached edid before overwriting
the new one.
