drm/bridge: analogix_dp: Reuse &link_train.training_lane[] to set DPCD DP_TRAINING_LANEx_SET

Browse Source 
In analogix_dp_link_start(), &link_train.training_lane[] is used to
set phy PE/VS configurations, and buf[] is initialized with the same
values to set DPCD DP_TRAINING_LANEx_SET.

It makes sense to reuse &link_train.training_lane[] to set DPCD
DP_TRAINING_LANEx_SET, which can remove the redundant assignments
and make codes more consice.
