ipa: ipu3: af: Auto focus for dw9719 Surface Go2 VCM
Since VCM for surface Go 2 (dw9719) had been successfully driven, this Af module can be used to control the VCM and determine the focus value based on the IPU3 AF state. Based on the values from the IPU3 AF buffer, the variance of each focus step is determined and a greedy approach is used to find the maximum variance of the AF state and an appropriate focus value. The grid configuration is implemented as a context. Also, the grid parameter- AF_MIN_BLOCK_WIDTH is set to 4 (default is 3) since if the default value is used, x_start (x_start > 640) will be at an incorrect location of the image (rightmost of the sensor).
