Hi Lee,

Thank you for the patch.

The driver has other functions related to link training that start with
the zynqmp_dp_link_train_* prefix. I'd prefer renaming this function to
zynqmp_dp_link_train(). Bonus points if the same patch could rename
zynqmp_dp_train_loop() to zynqmp_dp_link_train_loop() too :-)
