[U-Boot] [PATCH] Revert "T2080QDS/PCIe: Soft Reset PCIe on T2080QDS for down-training issue"

[Zhao Qiang]

This reverts commit 5066e62847bddf6030262ade2aa3e7bcdc930037.

The reverted patch will block t2080RDB iNiC, it was a workaround for
T2080QDS
down-training issue, we need to revert it and find the root cause for
T2080QDS
down-training issue.
