media: imx-mipi-csis: Implement .init_cfg() using .set_fmt() 

The .set_fmt() handler is responsible for adjusting the requested format
based on the device limitations. Implement .init_cfg() as a wrapper of
.set_fmt(), to ensure that the initial configuration always matches the
rules implemented in .set_fmt(), should they ever change.
