media: hi556: add 2592x1444 resolution 

Adding additional cropped 2592x1444 resolution
for QHD output from Hi556 sensor

Also implement the get_selection pad operation for the Hi556 sensor driver.
The supported targets report the sensor's native size, the crop default
rectangle and the crop rectangle.
