Abhinav KumarandGreg Kroah-Hartman 0a20364829 drm/msm/dp: reset the link phy params before link training ...

[ Upstream commit 319aca883b ]

Before re-starting link training reset the link phy params namely
the pre-emphasis and voltage swing levels otherwise the next
link training begins at the previously cached levels which can result
in link training failures.
