accel/ivpu: Stop job_done_thread on suspend
Stop job_done thread when going to suspend. Use kthread_park() instead
of kthread_stop() to avoid memory allocation and potential failure
on resume.
Use separate function as thread wake up condition. Use spin lock to assure
rx_msg_list is properly protected against concurrent access. This avoid
race condition when the rx_msg_list list is modified and read in
ivpu_ipc_recive() at the same time.
