Encoding issue Wave5

A non-deterministic issue was discovered with the Wave5 encoder.

Tested on V9 + necessary changes (DT entry, Kconfig adjustment and get irq change) https://gitlab.collabora.com/chipsnmedia/kernel/-/commits/wave5_V9_base/

TEST COMMAND

for i in 1 2 3 4 5; do echo -e "\nRun $i\n"; gst-launch-1.0 videotestsrc num-buffers=300 ! v4l2h264enc ! h264parse ! qtmux ! filesink location=test.mp4; if [ $? -eq 1 ]; then echo "FAIL"; else echo "CORRECT"; fi; done

So far, I have found three different issues:

Internal data stream error in gstbasesrc

ERROR: from element /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0: Internal data stream error.

Buffer has no PTS

The issue is not determenistic:
