2019-12-05drm/amd/display: Change the delay time before enabling FECLeo (Hanghong) Ma
[why] DP spec requires 1000 symbols delay between the end of link training and enabling FEC in the stream. Currently we are using 1 miliseconds delay which is not accurate. [how] One lane RBR should have the maximum time for transmitting 1000 LL codes which is 6.173 us. So using 7 microseconds delay instead of 1 miliseconds.

2019-12-05drm/amd/display: fix dprefclk and ss percentage reading on RNEric Yang
[Why] Before was using HW counter value to determine the dprefclk. Which take into account ss, but has large variation, not good enough for generating audio dto. Also, the bios parser code to get the ss percentage was not working. [How] After this change, dprefclk is hard coded, same as on RV. We don't expect this to change on Renoir.
