This patch fixes following compilation warning:
CC [M] drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.o
drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c:1733:12: warning: ‘s5p_mfc_get_decoded_status_v6’ defined but not used
It assigns existing but not used s5p_mfc_get_dec_status_v6() function to the
get_dec_status callback. It seems the get_dec_status callback is not used
anyway, as there is no corresponding s5p_mfc_hw_call().

MFC v6 needs minimum number of output buffers to be queued
for encoder depending on the stream type and profile.
The patch modifies the driver so that encoding cannot be
started with lesser number of OUTPUT buffers than required.
This also fixes the crash happeninig during multi instance
encoder-decoder simultaneous run due to memory allocation
happening from interrupt context.

Add support for V4L2_DEC_CMD_STOP command which will instruct MFC device
to finish decoding and release all remaining frames kept for reference to
the user. After dequeueing last decoded frame the driver will generate an
V4L2_EVENT_EOS event.

Change internal buffer allocation from vb2 memory ops call to direct
calls of dma_alloc_coherent. This change shortens the code and makes it
much more readable.

Checking unsigned variable for negative value always returns false.
Hence make this value signed as we expect it to be negative too.
Fixes the following smatch warning:

s5p_mfc_set_enc_ref_buffer_v6() warn: unsigned 'buf_size1' is never

Flushing of delay DPB buffers have to be done during stream off.
In MFC v6, it is done with a risc to host command.
