[Linux Device Driver] tasklet control functions

tasklet is used for implementing bottom-half interrupt handler to handle heavy and slow interrupts

tasklet_enable: enable tasklet
tasklet_disable: disable tasklet
tasklet_disable_nosync: similar to disable_irq_nosync. disables tasklet without waiting the completion of currently running tasklets

tasklet is not re-enterant similar to interrupt service routine
