video: tegra: host: add sof/eof timestamp support

Browse Source 
[1] Fills SOF/EOF timestamp buffer action before SOF/EOF
    signal actions.
[2] Adds action opcode ACTION_WRITE_TIMESTAMP to inform
    firmware for scribbling timestamp buffer.
[3] Decrement MAX_TASKS_PER_SUBMIT from 24 to 16, since existing
    results in stack size > 2048 byts (overflow).
