a52sxq: sensors: Toggle touchscreen on/off if needed

Browse Source 
* Due to config_powerDecoupleInteractiveModeFromDisplay we need to wait for the sensors sub HAL to re-start every time we fail a fingerprint unlock with screen off or on AOD.
* To prevent killing said overlay and having the touchscreen constantly enabled on AOD, we simply toggle the touchscreen on/off with every screen-off-UDFPS unlock
