video: tegra: host: disable MPE auto-power-gate

It is seen that auto-power-gate of MPE causes some issues when long run
camera stress test is run. The issue manifest itself in the form of
MPE sync-point not getting triggered from hardware and hence the caller
who is waiting on it hangs up the system.

Disabling auto-power-gate for MPE seems to resolve this issue.
