This is just for pre-production hardware, and we don't implement
workarounds for pre-prod.
A quick r
According to BSpec, cdclk has to be not less than 432 MHz with DP audio
enabled, port width x4, and link rate HBR2 (5.4 GHz)
Having a lower cdclk triggers pipe underruns, which then lead to displays
continuously cycling off and on. This is essential for DP MST audio as the
link is trained at HBR2
