drm/panel: simple: Drop prepared_time

Browse Source 
This has been superseded by RPM in commit
3235b0f20a0a ("drm/panel: panel-simple: Use runtime pm to avoid excessive unprepare / prepare")
and the last user of the non-RPM case has been dropped in commit
b6d5ffce11dd ("drm/panel-simple: Non-eDP panels don't need "HPD" handling")
whatever is left in this driver is just assigned and never used.
Drop the remaining parts.
