drm/panel-samsung-atna33xc20: Extend autosuspend delay

Browse Source 
Avoid the panel oscillating on and off during boot. In some cases it
will be more than 1000ms between powering the panel to read the EDID early
during boot, and enabling the panel for display. Extending the
autosuspend delay avoids autosuspending during this interval.
