video: tegra: host: Implement MPE context switch
Implement context switching for MPE. This allows doing multiple video
encodings at the same time.
Context switching relies on wait base being in sync with sync point. As
MPE user land does not use wait bases, the patch also enables automatic
wait base syncing.
This patch does not enable the context save/restore.
