tsec: Don't disable HOST1x clock because it's used

Browse Source 
Tsec keys function always disabled host1x clock after running.
This interferes with display interface and disables further window frame syncing.
Display_end code already handles disable and reset of said clock.

It also fixes an ancient bug that was mitigated by removing the 5 frame sync on HOST1X_SYNC_SYNCPT_9 at channel 0:
