MLK-18273 VPU: Modify behavior of end of stream for decoder

    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
