tegra124: add support for full DP link training
The original dp driver supports only fast link training and a
special drive setting is used for the link training sequence.
This might not be accepted by all panels. The better way is to
go through full link training sequence to negotiate for a best
drive setting.
With the change, dp driver will try fast link training first,
this is same as before. If it fails in fast link training, will
try full link training.
BUG=chrome-os-partner:32129
TEST=all panels on blaze/big devices work fine.
