The patches have been successfully tested on a Mackerel board with the on-board

Add a capabilities field to the soc_camera_host structure to flag hosts
that support user-configurable line strides. soc_camera_try_fmt() then
passes the user-provided bytesperline and sizeimage format fields to
such hosts, and expects the host to check (and fix if needed) the
values.
Instead of computing the line sizes, use the previously negotiated
soc_camera_device::bytesperline value.
