> Each DP link training contains link training 1 followed by link
> training 2. There is maximum of 5 retries of DP link training
> before declared link training failed. It is required to stop link
> training at end of link training 2 if it is failed so that next
> link training 1 can start freshly. This patch fixes link compliance
> test case 4.3.1.13 (Source Device Link Training EQ Fallback Test).
