tegra124: use known-good drive for fast-train only
A higher drive setting is used for fast link training, once the
link training succeeds, a known-good drive setting will be used
for the main stream transactions.
For full link training sequence, the sink devices may ask for a
preferred drive setting, thus this drive setting should be used
for the main stream transactions too.
BUG=chrome-os-partner:32129
TEST=all panels on blaze/big devices work fine.
