1177b17bdb smcinvoke: Handle suspend and resume issues in smcinvoke driver
This change makes changes to smcinvoke driver to handle suspend and resume
scenarios. If the accept thread gets interrupted, do not set the server state
as defunct if the thread is in freezing state, i.e. if the thread is going in
suspend. In such cases, increase timeout of that server so that invoke thread
waits indefinitely for response from userspace until the system resumes back.

Tests:
1. Stability testing has been done on kalama.
2. smcinvoke vendor client testing is done on pineapple.

ef2c3ba718 smcinvoke: ADCI changes for SMCInvoke Driver
Change consists creation of ADCI thread at SMCInvoke
driver initialization

 Change consists creation of ADCI thread at SMCInvoke driver initialization
 Following scenario have been tested for this change
  (1) ADCI thread creation and QTEE invocation during driver initialization
  (2) Backward Compatibility - IF ADCI feature is not supported (OBJECT_ERROR_INVALID)
        then exit the ADCI thread gracefully after cleaning up all the resources
  (3) Leak Test: All the resources held by ADCI thread should be released if ADCI feature
      is not supported by QTEE
      (i) adci task_struct state and exit state:
            state =  TASK_RUNNING , exit_state = 0 (While ADCI thread execution)
            state =  TASK_DEAD , exit_state = EXIT_DEAD (During ADCI thread termination)
     (ii) adci task_struct = NULL (fetched based on adci thread_id) which make sure
             task_struct has been deallocated
  (4) SMCInvoke related Test: All the internal(suuported),memobj and cbo testing has been performed.
