The MIPI_DSI_CLOCK_NON_CONTINUOUS causes visible artifacts in high

I can't see these artifacts in 1920x1200 24bpp, but still looks good to me

I have to retract that. After checking for those mentioned artifacts
I noticed that the DP output was running without any issues.
There is something more going on here. Reverting this patch there wasn't
a single output problem.
This changes actually breaks my DSI connection randomly.
Sometimes it works, sometimes not. I also noticed that there wasn't even
a single DP link training failure, so I assume the DSI clock somehow
affected the internal state machine which even affected DP link training.
Until we know what's going on, NAK form me.
I can temporarily drop this patch and keep the remaining five if that's
OK with you ?
