video: tegra: dc: Fix hang in dc reset
When DC(Display controller) meets underflow,
DC needs to be reset to recover this,
but in several resets, it hangs.
To avoid this,
- Set DC STOP mode ahead of DC reset assert
- Off read host bus by DC ahead of DC reset
- In DC0 reset period, to avoid DC1 access
and vice versa
- In reset worker, do not try to off host1x
