drm/panel: simple: Correct G190EAN01 prepare timing

The prepare timing specified by the G190EAN01 datasheet should be
between 30 and 50 ms. Considering it might take some time for the
LVDS encoder to enable the signal, we should only wait the min.
required time in the panel driver and not the max. allowed time.
