Feel free to include this tag for this patch in future revisions.

By moving the Display On/Off calls outside of the suspend sequence, the racing conditions that made the Ally controller suspend unreliable are completely fixed. This includes both when mcu_powersave is enabled and disabled. Therefore, remove the quirk that fixes them only when mcu_powersave is disabled.
