security: tf_driver: update with latest TL drop
This change fixes abnormal signal handling in tf driver.
Tf_daemon(user thread) is waiting for the signal when coming out of LP0,
but tf_daemon never gets the signal because tf driver can't handle the
signal properly. If there's a pending signal when coming out of LP0,
this fix clears the pending signal.
