Reader function lost after screen off CE.

Screen state update command and corresponding discovery loop was not working
properly with the below test case scenarios are handled.
1.RF discover loop contains only listen Tech when turn of the RF field after changing
the screen state,Polling part was not updated in screenon unlocked.
2.screen off->field On->Activate Idle->RATS+PPS->RF Field Reset->Field off
->Screen On -> Hanged.
3.If RF Filterning Enabled (A602=01)
 screen off->field On-> Screen lock->Screen On->Screen Off -> Hanged.

Below are the changes added.
1.In case of if Field On is not received before activation, consider NFA_ACTIVATED_EVENT for
 locking the transaction and use Field Off received while removing the reader from proximity to end the lock
 has to handle this for all chipe type not only for PN551 and PN548C2.
2.Clearing the all pending request if already handled.
3.Transaction state has to check for NFA_TRANS_ACTIVATED_EVT if RF field interface
activated but not done any transaction.
4.Abort Timer has increased from 10 sec to ~15 mins to avoid double beep
If we hold the reader continously more than 10 sec.
