Allows SM6125 to use the common Lineage camera HAL without any source edits. Shifts the camera struct for laurel_sprout to avoid get_cam_pos. Edits metadata for ginkgo/willow to properly register ID 61 logical camera. Change-Id: Iabf37484a401e63dcbcebac3db6bfbd898d78b1f Signed-off-by: Skyblueborb <tomaszborbely0710@gmail.com>
