Fix some decoder and encoder code bugs as follows:
- change vpu_stop_streaming to prevent deleting repeated entry
- reduce wait time for encoder from 5s to 1s
- change vpu_suspend to correct the calling of vpu_set_power() function
- change vpu_next_free_instance() to depart QM from QXP

Change behaviour of end-of-stream behaviour. When application signals stream
feed complete by sending a V4L2_DEC_CMD_STOP, rather than immediately inserting
the EOS marker into the buffer, instead set a flag to do the insertion on the
next LWM from hardware. This involves both driver and firmware changes.
New flow
-------
1. Receive V4L2_DEC_CMD_STOP, set ctx->stream_feed_complete = true
2. On next VID_API_EVENT_FIFO_LOW call add_eos() to insert an EOS
and padding. Set ctx->eos_stop_added = true
3. On VID_API_EVENT_FINISHED generate V4L2_EVENT_EOS from driver
Additional control also present to ensure that...
1. If an abort is triggered prior to the end of stream EOS marker
being added, then the EOS is not added by driver
2. If an abort is triggered after the driver has inserted the EOS
marker to signify end of stream then the abort is ignored

- Check ‘firmware_stopped’ before send eos when receive
application end of stream command
- Add calling of ‘v4l2_update_stream_addr’ on stream on
- Add check before calling abort command
- Not call add_eos for abort command since firmware will insert
eos locally
- Insert mb() for command/feed_data operation
- Move ‘v4l2_event_queue_fh(eos)’ from VID_API_EVENT_STOPPED to
VID_API_EVENT_FINISHED
- Add ‘firmware_finished’ in VID_API_EVENT_FINISHED
