drm/panel/s6e3ha2: fix initialization sequence
Panel datasheet is not clear about it but directly after dsi interface
setting and calibration of panel, DSIM/MIC should start transmission, panel
should then wait 120ms and finish its initialization.
The patch fixes frequent image loss on draco board.
