gpu: ipu-v3: Add Camera Sensor Interface unit
Adds the Camera Sensor Interface (CSI) unit required for video capture. Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Removed the unused clk_get_rate in ipu_csi_init_interface and the ipu_csi_ccir_err_detection_enable/disable functions. Checkpatch cleanup. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
