[ Upstream commit 1ed36ecd1459b653cced8929bfb37dba94b64c5d ]
To comply with the intended usage of the V4L2 selection target when used to retrieve a sensor image properties, adjust the rectangles returned by the imx219 driver.
The top/left crop coordinates of the TGT_CROP rectangle were set to (0, 0) instead of (8, 8) which is the offset from the larger physical pixel array rectangle. This was also a mismatch with the default values crop rectangle value, so this is corrected. Found with v4l2-compliance.
While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and CROP_BOUNDS have the same size as the non-active pixels are not readable using the selection API. Found with v4l2-compliance.
[reword commit message, use macros for pixel offsets]
