media: imx: imx-mipi-csis: Implement the .get_frame_desc() operation
The CSIS is connected to its sink through an SoC-specific gasket that
needs to be configured. Depending on the platform, the gasket
configuration requires knowing the CSI-2 DT. To provide the needed
information, implement the .get_frame_desc() operation.
