DLKM: touch: Improve novatek 0flash driver

- Add interface for RF desense test.
echo 0 > /proc/nvt_monitor_control，touch keep in active (Normal Active)
echo 1 > /proc/nvt_monitor_control，touch keep inactive + doze (Normal Idle)
Press power keep or let phone enter into suspend, touch keep in sleep or power
