drm/bridge: ti-sn65dsi86: Add mystery delay to enable()
This patch adds a 70ms mystery delay to the bridge driver in enable. By experimentation, it seems like it can go anywhere up until we initiate semi-auto link training. If we don't have the delay, link training fails. I tried to root cause this as best I could, but neither the datasheet for the panel nor the bridge mention a delay of this magnitude in their timing requirements. So for now, add the mystery delay until someone figures out a better fix.
