ST VGXY61 camera sensor driver

The ST VGXY61 driver implements the following controls:

`V4L2_CID_HDR_SENSOR_MODE`

Change the sensor HDR mode. A HDR picture is obtained by merging two
captures of the same scene using two different exposure periods.

.. flat-table:: :header-rows: 0 :stub-columns: 0 :widths: 1 4

* - HDR linearize
  - The merger outputs a long exposure capture as long as it is not
    saturated.
* - HDR subtraction
  - This involves subtracting the short exposure frame from the long
    exposure frame.
* - No HDR
  - This mode is used for standard dynamic range (SDR) exposures.
