video: tegra: host: Keep wait bases in sync
Add opcodes to synchronize the wait base for each channel at the
beginning of each submit. This adds robustness towards misbehaving user

Context clear for robustness clears the opcodes for synchronizing the
wait base. This change also removes that part of robustness.
