[Port from R2] atomisp: The screen flashed green when changing state of back camera.

BZ: 31998

We need to re-calculate ITG value when changing state also resolution.
When changing state or resolution, sensor settings are changed.
Itg value is depend on the sensor settings; frame_length_lines, line_length_pck and read_mode.
If use previous itg value without re-calculation, itg may be invalid.
Invalid settings of sensor generates some kinds of bad frame.(i.g. green flashed frame)
For the same reason, we should remove the restore exposure block in mt9e013_s_mbus_fmt.
The previous itg may be not correct value.

Solution :
- atomisp
  improve 1'st frame image
- libmfldadvci
  improve 2'nd frame image
- libcamera
