Thanks, I have added the Fixes tags and re-pushed.

I have added only sm8650's tag and another change which re-used sc7180's 
dp_descs without retaining the widebus_supported bit.

The reason I didnt add others is because widebus support itself was 
added only later to DP driver compared to the other ones.

If I am missing any Fixes tag, pls let me know and I can fix it while 
applying.
